Well hell! I ordered a set of Promaxx heads a few hours ago because I need them ASAP... I'm not doing any work on them myself, just wanna bolt them on and drive... I'm gonna try to cancel it and order a set of Kings I guess, from what I've seen they have a decent reputation.The valves, etc that came on my Promax from J&C Enterprises are beyond garbage, and partly responsible for my rebuild.
J&C recycles used valves, springs, etc from old heads and drops them directly into new ones. Three of my valve springs were DOA.
Promax themselves are fine, just need finishing work. No idea about King tbh.
Edit: Wait, do you mean you purchased the heads from J&C, with their recycled valvetrain? I understood it as you purchased from Promaxx's website and they had shitty recycled valves and springs... The amount of research I'm doing hurts
Edit again: Talked with a Promaxx rep over the phone. They use brand new SBI parts on the new head castings. Sticking with them.
