    What do you think about the whole "cutting and welding of two 350 heads to make a single 292 head?" I have two spare 350 heads that have 1.95 and 1.55 valves in them already?

    Get a hold of Mike Kirby at Sissels in West covina CA.He was making some pretty cool aluminum heads for the chevy 6.I have his number here somewhere if you cant find it online

    Bruce Sizemore is the guy back in the day that did this to a Ford 300 6 cyl. truck engine with Cleveland head conversion.

    Have a read of the story on this link.

    The big reason to do the sbc heads is ...options....opens up lots of flow tech.....far..far...above what you can do with a stock head.....there are some real great aluminim heads out ther for the six....but think of the options ya have with the sbc set up.......lots of work ...for sure....I drive Leos car......and I can tell ya...that set up peeeeels
