This is continuation of another thread but I thought it might spark more discussion if posted separately.

I've been doing some research lately on 350 builds. Wondering if anyone has experience with using the higher compression small valve heads on a 350 and with what result?

The heads won't have clearance issues like big valve heads and would seem to be a great option. Common castings would be the #46, #18, #48, 1970 #16, and 1968 #15. I see a lot of these for sale fairly cheap. The 400 and 455 guys want big valves so these heads are kind of in limbo. But for a 350 build?

One issue might be too much compression but several ways to bring that down to higher octane pump gas levels without much issue.

Thoughts? Experience?
