Another low budget 360 build

Build the engine with quench or don't.

Quench is the described as the very tight clearance between the top of the piston and the bottom of the cylinder head. This can best be seen or imagined when a flat top piston is at zero deck height, (dead even with the deck of the block) and the head gasket is thin, (think .045 or less & less is better)
And the cylinder heads flat spot is over the piston. Think Edelbrock heads and there small chamber. A lot of the head is a flat area.
That flat area over the piston is the quench area.

OR

Move the piston down the cylinder (AKA Low compression slugs) or move the head up, as in thick gaskets. This prevents detonation.

A good quench engine doesn't have this issue of detonation if used correctly.[/QUOTE]


so would I be better off with H405cp pistons and a thicker head gasket or even stock cast with thinner gaskets? would there be much of a difference in performance?
So how do you achieve quench with open chamber heads without running high octane fuel?
I was originally looking at running higher compression with H116cp pistons. Could I get away with these and open chamber heads using the other components listed above and run 89 or 91 octane fuel?
I'm very mechanical but get stumped on calculating stuff like this.
I just want to build a good running reliable engine that has enough power to play with when I want to.
Thanks for your time
