And after learning that a rougher texture makes a port behave smaller I'm going to try going extra rough on a set of heads that are considered pretty large for the size engine. Certain parts smooth of course, like the short turn.

🔔😎🇺🇸 21:30 It's often been said... 80% of the gain is from the first 20% of your time. Going for the rest of the 20% gain takes TIME. And... The greatest port restriction is the partially closed valve. 🤔🤔

Great video! Your approach, honesty and critique are spot on and treats the individual with respect, and as a MATURE learner. You will learn more from failure then you will success, if you are willing to learn. Some of the comments I see on this video are just plain disrespectful and small minded. Small mindedness and poor manners are why you will not learn from your failures. Eric... Thanks. I appreciate your polite candid critique, your willingness to share tradecraft, and humility to understand others have different opinions, or may know more than you. This video in particular gave me pointers on how to check the work of the people I higher to do the performance improvements I cannot do on my engines. Keep the videos coming!

Fantastic video. The last time I ported heads, I was reading a magazine to get a general idea. When I did the heads, I always did the intake manifold at the same time. I did 302/351 heads with stock/Cobra intakes and I would reshape the first runners with the most length and curve by using Metal Lab as a filler to keep the runner diameter the same. Didn't know what I was doing but the good news is that with a stock head and intake port, it was very obvious that the cars made good power as the walked away from the car they lost to the week before.

I always use straight Newen/Serdi carbide pilots for seat cutting. It eliminates all the problems of tapered pilots. Although tapered pilots can be used if used properly. I never push in tapered ones hard. A light touch of tip of the finger should do. As pushing a tapered one hard in will make the pilot being bent so the seat runs out of centre.

That’s some very good information. It would be interesting to see where the flow starts dropping off past .600 lift. While that’s not desirable for a full race job, there’s a lot of street applications where maximizing the flow at or before.600 is a good thing.

I will be subscribing, and will definitely be checking out other vehicles. I have every belief that with the attention to detail in this porting critique, I will definitely be looking for a video about why it’s so important to also port match an intake to heads as well. Good stuff!

It's just my guess but I don't see why that would matter. I believe his percentage numbers were "general" numbers and I would guess that percentage ratio is flowed without valves to evaluate the port itself....but I'm not an expert by any means.
