I have race teams with more than one championship on promaxx heads. If you arent buying dart, brodix, or profiler, buy promaxx and be happy.

I noticed AFR missing from that list?

Not on purpose. I have AFRs on the engine in my boat, and our race boat. They're an awesome product.

flotek/promax 290cc good port is turbulent out of the box, reshaping the head bolt pump inside the port fixed the problem in flotek 290cc heads.
