ok, i just did a quick search on why a tighter quench is better. the closer the piston comes to the bottom of the head creates more turbulence, and turbulence reduces detonation

another good one.... I'm talking about serious nitrous motors not a pump gas 150 shot car.

i wonder how this would be applied to E85, as thats what im trying to learn about and switch over too for a nitrous
there was dyno on a sbc on another forum that sprayed a 300 shot on an e85 motor and his EGTs were 1100*F. they said on motor with regular gas EGTs are usually in the 1200-1350*F and upwards of 1500*F on spray.
i wonder if you would want to run a tighter quench on a nitrous motor on E85 that burns a lot cooler.
i never knew the guys running big shots went with a much larger quench. but thanks for explaining why

61 i think on the gm 60L gaskets.
Waynes dead on on the gaskets. we were in your guys boat a while back and my car was making alot of excess heat. after talking with some experts they told us to bring the quench to .051 and it helped alot. we also run at leact .060 bigger than the boar to get the lip of the gasket back from the heat. Tony Mamo had us do that and we have never had a head gasket fail or leak.
BTW you should never use head gasket to make or losten compression only to set quench a the optimal distance.

the heads being milled doesnt matter, do you have a build sheet on your shortblock? or did you put it together yourself?
all the matters is your gasket thickness and where your piston sits.

So how do you find out how much the piston sits out of or in the bore? And i'm assuming if the block was decked and the heads were milled you have to add that in also, right? Just curious what mine is, if the gasket is .061 my block is decked .010 and the heads are milled .020, so depending on what the piston does i'm already at .031 before any other changes, right, or am I on the wrong track here?
Post #25 is what your looking for I think!!
doesn't running a bigger bore gasket help with the "fire ring." I've been told to run a .010 bigger gasket to help with the heat, which helps the gasket from blowing?
