Personally, anything that says "ProComp" on it gets a thumbs down from me. Many yearns ago when the brand first started showing up in some parts dealers, I thought "oh, goody, more reasonably priced things"; then I started really looking at the stuff: it was all poorly finished literal copies of items that were designed and originally made in the USA by reputable companies like Weiand, Edelbrock, etc. I think they must have used an original to make their molds with; but if you put an original Edelbrock valve cover along side of a ProComp that looked just like it, you could see the similarities, AND the differences. At that point, ProComp went from inexpensive to cheap in my estimation. Sure, it looks like the real deal, but - - - - - ????
