ProComp/Speedmaster aluminum heads

Hopefully Tony chimes in again. He has had a few sets done and seems happy. There is more than a few guys running these and some I’m sure ootb. So a little help should do wonders for these heads. There will always be the Chinese haters. But I bet if u looked in there drive way, house, shop u will find 75% Chinese appliances, electronics and tools etc. Oh ya, on or in there pride and joy American made Mopar. Kim
