mrperformanceparts heads - Pro Comp?

Hello all,

I found a set of big-block alluminum heads on ebay produced by a company called MrPerformanceParts. So I ran a search on moparts to see if anybody had discussed them and someone had written that they were basically the same as pro-comp heads, which were an Edelbrock Victor copy. In any event, I was wondering if anyone has any experience with any of these variants, especially the ones sold by MrPerformanceParts. Any information is helpful and greatly apreciated.

Thank you

Are they that much cheaper than the real Victors to make it worth the chance...

the they come with screw in rocker studs told me what i needed.
