LA 360 budget build ideas

Why you say not to zero deck it? I figured that would help improve the compression ratio, flame travel, quench. Isn't a good quench distance better for preventing detonation?
Because the KB-107 slugs come in decently high and the usage, as you said, is f a .028 head gasket on a zero deck engine and iron heads @ 72 cc’s, IF you have a 72cc head, is 9.8-1 or better. With a small cam, the cylinder pressure is very high and no amount of quench will solve your pinging problems. You’ll have to dial back the timing in order not to ping even with 93 octane and you’ll end up loosing a lot of power.

I plan on having the block bored and honed with tork plates as well as having the rings file fitted while the torque plates are still on the block, what do you think?
File fit the rings without a torque plate on.
