I was wondering.....do they use different angles depending on head style or is it a one size fits all kind of deal?

the way I understood it was they won't to leave a .200 quench pad from the bore size . how deep they go before with the cut I don't know

Re: combustion chamber softening
fast forward told me that on a 3 degree the next mill job would probably cut that out and that the 10 degree is more affective

Re: combustion chamber softening
I failed to ask if it would even be worth doing on a 350 to 400 shot , a lot of stuff I read people are doing this on multiple kits to help the engine live

One degree doesn't take but .0175" per inch. So, starting .200" off the bore and going but 3* would not get one much on a chamber like the SCJ deal on the right.

Lem, you're getting soft chambered in your old age.

Naw....I'd just jack the piston down in the hole
Re: combustion chamber softening
yes the 3* cut is a waste of money with the big shots of nos.the 10* or bowl cut is what most use in combonation of droping the piston in the hole for the big nos shots.

Re: combustion chamber softening
race gas is a little cheaper than aluminum. Might want to add a little fuel.
