I've read lots of negative feedback about Procomp heads on the 460ford.com forum.You're better off with a quality brand than a cheapo imitation.Those are less than half the cost of a pair of heads from a reputable manufacturer.Makes you wonder what "shortcuts" had to be made.
Look like Pro-Comps to me. I have a set that I haven't installed yet. Decent "stock" type re-placement if you have EVERYTHING on them checked before installation. NOT meant to be a "performance" or "race" head.
Are you looking at the ones from J&C enterprises That sure is a nice price for a complete set of built heads. Does anyone here have them they have sold several sets on e-bay this year and I dont see any negative feed back. Im new what if anything do I need to put in the title block for replies?
