Hello Z28 Buddies. Well, here is my first post. I want to see if this is possible on hot motor build sbc 4" bore. Installed a 485 lift solid cam (original 69Z28 grind specs) and 110 petro and 3600-4200 stahl. Would like to use L98 aluminum heads (10088113) 57cc on my sbc with Wiseco dome 4.040 pistons (installed). .035 mls gasket and 3" stroke. Setting the head on I see the dome pushes against the structual rib that's by the spark plug hole inside. Can I grind the rib down for clearance and not worry about structural damage to the head. I have cast heads also, 365 F.I. and also 882's that will probably fit fine. I think I know I'll have high compression motor but don't know exactly how high. I've never used an aluminum head and would like to try this set-up if it's possible. Any help would be greatly appreciated. I'm trying to stay close to original 69 Z28 302 GM Specs. I just don't have enough experience and knowledge to know.
Thanks...T.J.
