I'm assuming you're talking about these guys.

Unfortunatly they don't differentiate between SOHC and DOHC motors. Granted both blocks accept the same pistons but without know which head they were intended for and tested on it's hard to know what the actual compression will be unless you call and they know.
This quote from their website isn't very reassuring either.
"• HI-PERFORMANCE and RACE ENGINES• SEVERE TURBO and HI-COMPRESSION VERSIONS• TIGHT CLEARANCE for REDUCED PISTON SLAP• ALL PISTONS ARE 2618 ALLOY and ‘NOS’ COMPATIBLE• CONTACT REDUCTION and PRESSURE SEAL GROOVES• PINS and LOCKS INCLUDED "
Of note are "severe" turbo applications and "NOS compatible."
NOS is copyrighted, by the way, so does this statement mean it won't work with ZEX kits?
