Thanks! Appreciate the kind words!!

These videos are what earned my trust to send my cylinder head to them. Good for business.

@@kalyndyck315 I can understand that completely. I can't agree more. I've been a machinist for 2 decades doing everything from automotive to aerospace. The knowledge shared speaks volumes about their experience. And this isn't the kind of info you can read in a book. It comes from LOTS of trial and error

@@highpsiguy4085 funny you say that. When I started this journey, I felt like people would theory but I just couldn’t do speak about anything but experiences.

@@headgames from someone in the same "trade/profession" I could tell immediately that you were very skilled and very knowledgeable. I believe strongly that even the average customer watching your videos has the same feeling. Even without the machining background. And that speaks volumes. I'm sure there's quite a few people that come for the content and leave as a future customer. Because you build a relationship THROUGH the content you post. And that's priceless!

thanks!

Ben thanks for the kid words! We don't port that head either. It really doesn't need it for what most do with it. A good valve job and a pocket port and it rocks.

@@headgames Thanks for the reply Dave, Good to know! Curious on your thoughts on the M54 head. Couldn't help but notice when I had both heads on the bench next to each other. Both the intake and exhaust ports on the M54 head are considerably smaller than the S52 heads. My application is road racing and its NA. Torque off the corners is important but so is straightaway HP and speed. Always a balance. It seems like BMW started focusing more on low end drivability (AKA torque) in the mid 90's as they first reduced the cross-sectional size of the S52 intake manifold as compared to the prior generation M50 manifold. A popular swap among us BMW S52 guys but I question the loss of mid-range torque, I'm thinking from loss of air speed. When the M54 came out, again another reduction but this time in the size of the ports. Does Head Games do anything with the M54 head with porting considering the factory port size of the S/M 52 head is much larger? I'm on the fence on what engine to build out and therefore what head to send you guys. M54 engine is aluminum and takes 40 lbs. off the front of the car however, if the engine can't be made to breathe that is another issue. It would seem that even though they made the ports smaller, the performance numbers went up. Is that velocity over volume thus supporting your direction on "bigger isn't always better? Last question, vanos fan or not? How does vanos effect air flow if at all? Love your videos Dave, like to see more BMW stuff of course but I'm probably late to the game on that one, they seem to be old school

Next vid I do!

thanks sugar!

Not with the grinder but yes. We machine that area. Don't try to make the area under the seat that a lot of 4G heads have that is deeper than the rest blend in. You will make it too big.

@@headgames I've seen some where the casting meets the seat are actually bigger, in that case would I need to blend the seat to the port ?

That sounds terrible but cool you liked it! Bret is good people too.

@@headgames haha Yes Bret is a cool guy. I fugured you knew him lol

We are always replacing the guide when we are porting. But, certainly you can knock them back out of the way if you don’t want to replace.

A lot of our videos touch on this. There is no real hassle, because if you are doing a valve job it is just setting the cutter to a different diameter. The issue is almost every head we have tested it does flow better to do +1 but only after 9mm of lift. And under that lift, the stock size valve destroys the +1. So the area under the curve is much better for the stock size valve. Same thing happens on the car.

Don’t believe that hogwash. You wouldn’t be able to replicate the same block, same sleeve in a machine. Some shops are torquing the heads to a plate for the valve job but everyone would have to if what those overthinking window lickers were correct. They are also the guys who leak the engine down before start up. Like there’s an actual leak down standard for that. Great question! I think it’s a video idea

@@headgames Thankyou so much for clearing this up for me. Watching your video's has already cleared up so many misconceptions for me. Like the video about going larger in the valves. The great thing is that you explained why. Really appreciate your help 🙏

you don't want to valve job the TFS heads. That valve job is tough to beat, and easily hurts CFM if you do. There is a ridge at the bottom of the intake seat that will kill airflow if you touch it.

@HeadGames Motorworks not trick flow just tricked out stock heads 😎

4G63 followed by 2JZ

The electric grinder sucks to sand with. I’ve tried it, easy way to bend the mandrel. No easy way out of that for you.

I would never use a stock valve and a ported head. Stock size, but not stock valve.

@headgames I'm guessing because material used in aftermarket stock sized valves are of better quality? Thanks for reply BTW

We are currently developing a b58 full port. Will be available in 3 months.

that is just measuring the guide that comes out and measuring the ones that goes in. We can do this! People don't measure, including the manufactures on this deal. Thanks for the input!!

Sorry we don’t have a full port for the 1UZ

We don’t work on them anymore. You can look up articles on ones we did many years ago for Modified Magazine and Import Tuner.

Yes!!

Thats obvious

Sorry not something we work on. I’ve actually never heard of either one before.

The head is in their Camry/Lexus ES300/330 from 97-2004. Its similar design to 2jz, but flows more on the intake unported. How about how large of intake valves can you install on 2jz?@@headgames

@@dennisrobinson8008 oh we definitely wouldn’t see any heads from that application for performance. I’ve seen guys do a +2 valve on the 2jz but we don’t do that. A oversized valve is not needed under 2000whp on a 2jz.

we do cylinder heads not tires

@@headgames Mine stalled on the road, doesn't appear to want to restart

​@@82_KID part it out

@@TDT0188 it was a loose wire on the starter

I have some L25 heads.... wanna check them out maybe for a video? They were supposedly reconditioned and sold from a Subaru dealer....Dealer.... @HeadGames Motorworks
