318 question

I'd suggest "doing the math" on the KB 167 vs the LA roller stock 9.2 piston to see if the extra .3 (or so) of compression is worth the expense.

Yes,

Also using the Mr. Gasket 1121G thin .028 ths head gaskets on the stock '89 318 roller 9.2:1 engine.

9.5:1 cr without a bunch of work, expence, and sourcing out correct parts is not all bad on its own.
