ZZ4 (L98) aluminum head with ROUND ports??
I have a set of heads on my floor (part # 10088113). They are the ZZ4 style head with screw in studs and green stripe springs. Only thing is, they have ROUND exhaust ports, not D ports. Anybody have an idea where these came from?

If he doesn't want to sale his, I have a set of 113's from my 91 that I removed a few years ago when I went to AFR's. They are already boxed up in the AFR Heads box.

Unless the newer GM 113 replacement heads (used on crate motorsthink they had a different PN but same head) had some revised port id say someone took a grinder to them at one time. Great big exit isnt where the gains are
