A major falling out on these ProComp heads is NO HELICOILS in the threads, just like their Victor rip offs. I would not trust the rocker shaft hold downs being threaded right into the aluminum. So you would have to add the cost of drilling out all the holes and installing heicoils into them. Now your looking at the same or more money than a set of Eddies.
IDK, cheap is cheap sometimes my 2 cents
