What compression would my stock b18c5 be at with their .030 head gasket?

 

it wouldn't change much b/c an oem 3-layer gasket is .0290000

 

ditto , wont change much at all.

 

Sorry, my brain fell out and I lost it.

 

you better have some copper spray and some ARP head studs to crank down. If not, have fun gettin it to seal. I've been through the Cometic HP and MLS, and now im gonna try out a Factory overbore.

But im also using a step deck RS block.
