Very good explanation! You kept it simple for those who may not understand the workings of cylinder heads.

The Truth from Danny a Master Craftsman thanks for your wisdom and skill

Thanks Danny - I inherited a head shop and now I have a starting point - thank you so much!

You Hit the nail (I mean Seat) right on the Head !! ....I See & Hear bout it done Wrong on Aluminium everywhere, Even on aftermarket Manufacturer videos !! .....Chilling & Heating for smooth, Easy force Insertion wthout Rolling seems Good, common Sense.....Big Thx for this Informative video Properly addressing this Huge Important shop Problem......

I like when you said if your going to short cut don't do it let somebody else do it. Your spot on saying it won't be profitable for you. The liability of short cuts is so expensive and always inconvenient.

Always nice work Danny. Thanks for sharing. Nice to see a real professional at work. Take care, Ed.

That’s right “if you’re not gonna do it right, don’t do it”. Laziness is bad.

Awesome job he knows what he's talking about. Listen to him. Learn what I needed to know. I know he knows what he talking about thanks. ....

Thanks Danny makes perfect sense to me do it right the first time!! Thanks for the video

Great job ,thanks for sharing 🇺🇸🏁

Thank you sir. great video 👍you took the words right out of my mouth . I don't have an oven but I do have a big enough grill with some wood and a baking sheet to keep the fire from toughing the cylinder head . freeze the seats for a couple hours and then go to town with it YEAH ! 😎

Great Explanation...💯

Thank you for your knowledge and video's USA 🇺🇸

Love it Thanks!

Maybe we can share with the engineers of my 3.7l dodge engine that had it wrong

Thank you very much

Is it OK if the exhaust seat is too close to the intake seat to flat spot them to fit in a cast iron head? I've never seen this before , usually the valves are far enough apart that this would never happen, I bought an engine fitted this way

I normally do cast iron, with integral seats. I try constantly to reuse the integral material. After all the years in service, the valves normally are the ones showing their "tiredness". Other than the integral seats being out of round, they normally clean up fast. However, I am constantly dancing valves around trying to get the recession acceptable. I have used .005 for cast iron, granted, I am less than a decade into my apprenticeship so I try to listen as often as possible. I have been heating and cooling when I do seats in cast iron. Is it stupid of me to do this? My cutters allow adjustment, and I felt smart that I knew about the part number being the bore size!! lol. I have many more questions, and would love to type them here for anyone else that might wonder. How often would you decide to try to salvage the integral seat rather than counterbore and press a seat in? Should the cast iron be much harder to seal than the seats? Cause I can seal an installed seat very easy,, sometimes those integral seats take extra effort for me. I acquired the mindset that everything gets "checked" at least. I was told in the past that lapping is the best way to check. What do you think? It is a sg8 from 2013 that I am using. I just stumbled across this video and ended up watching it,, so wth,, I figured I'd comment!!! Your channel is much bigger than mine btw!! Maybe commenting about specific things can get my channel a lil jump from your coattails!! lol

Hi i machined the seat on the lathe to fit my bore on the cast head. I did the torch method .Is it wrong to machine the seat?

Can you do the heads on my 3.7, I'm changing the engine out and seriously thinking of getting this done before installing the engine I bought.

I wish I had danny near me. I would send him my aluminum heads. I got a decent machine shop near me but I dont trust him with my aluminum heads besides resurfacing them. Cast iron blocks and heads I trust him completely. He mostly works on old hot rods.

Can you soldier a seat into the head?

Even on iron I put seats in freezer for a bit and go by .004 never a problem. Thanks don't see much aluminum here.

👍

Uh...1.733" minus 1.687" is .046". I'm pretty sure that's more "press" than you're gonna be able to "fit".

Amen brother, the world is loosing those that add the little things that develop the worlds best. 99.9 are interested in what sally is doing and why ted is not worried about sally. No one wants to teach and no one wants to learn. We are headed to a huge change. Thanks for the trade secret. It would have cost someone 3 years and 100k in college to learn that.

I thought the video was for showing us how to put

Ford FE head

That is exactly how not to properly fixture an FE head! You also failed to factor in your machine run out into your press fit equation Such as the spindle, chuck, worn pilot, worn wear sleeve on a Kwik Way machine and cutter deflection. I'm still waiting on my thousand dollars from your incompetent ring end gap video? ? I see that you never bothered to finish that series which tells me what I need to know!
