Re: Larger Dia BBC Thin Shim Head Gaskets?
This is getting tough, I found a GM gasket # 88961561 for the 572 motor, .030 thick. Still .008 away huh? This is a preflattened wire gasket for cast or alloy heads.
I know this is the extream, but I have heard of guys using a thicker babbit rod bearing on lower end of the rod cap and thinner on the other, thus moving piston up cly , few thousands resulting in More compression?
Other than the gasket company Tim recommend, thats all I know. Over and out.
