Is Quench Required?

Some people don't realize how much goes into dialing quench with pop-up or step head/step dish Pistons.
You either do your homework on the part combo and clue in your cam guy.. or you mod chambers to dial the static as to not have too much dynamic. 8.2 is right at the boarder of 'better know how to tune' and 'you should be safe'. Above that isn't for novice types or weekend warrior wrench heads.
Thinner gaskets going to raise the static and put you at 8.2 as you say, it will need a careful tune and that tune will need changing on the weather. Near .060 is negligible for effective quench. If you really want to effectively help squeeze n stir it up towards the plug.. ..028-.035 is doing it.
The sd's are .051-.054
8553 are .046-.049
1008 are .039-.042
They vary some if you measure them off a torn down motor after heat cycle.

I ran one 9.998 static and 8.8 dynamic, .030ish quench solid roller, 28 total timing on 91... just barely got by. It didnt ping.. but it didnt like it all that much. Made a ton of power.. but made more with 100 octane and sounded better. You would be better off with quench.. but by decking the block more and NOT relieving the chambers some to counter the comp bump put yourself into the temperamental build category. The gas in California sucks and many who live outside the golden state giving advice don't realize that all the time.
Anything you have to run less than 28 degrees timing and or above 34 na...is not a well planned build. Lol

Sound like quench was an afterthought.
