Re: Pro topline heads - aluminum
You sure those aren't Pro COMP or some other head? All the Protopline heads I've ever seen say Protopline on them and have a casting number.

Re: Pro topline heads - aluminum
They are the ones off ebay, the seller labeled them "Pro-Race"
Researching them I found that was one of a half dozen names with the most common being Pro topline
If you have a way to distinguish them otherwise, please let me know
No surprises

Re: Pro topline heads - aluminum

Re: Pro topline heads - aluminum
These are NOT Pro Comp
Pro Comp is a completely different casting
Look at the exhaust side, the mating surface is different
Look at the intake side, Pro comp is drilled for standard and vortec intakes, next look at the intake flange next to the water jackets, again different
Again these are NOT Pro Comp
My heads F/S

Re: Pro topline heads - aluminum
I don't mean to bust *****, but Protopline certainly have their name cast into the head. Protopline is NOT the same as ProComp, Pro Action, or any of the other "Pro" prefixed names.
Protopline, now known as RHS, are supposedly superior quality to the other Chinese-cast Pro-xxxxx heads.
