Does anyone know of a GT40X guru who can clean up the ports and make better flow numbers? I "fell into" a pair, but the casting quality is really bad. If I can find someone who understands these things that will do a good job at a reasonable price, I'd be interested.
I also wonder about the skinny (5/16" ? )rocker studs, will they hold up? Apparently so, it looks like the same head they put on the crate 392 CID engine.
Thanks,
