I was checking out some new pro comp heads on ebay for the big block mopar.

First time I see them.

Are these new? Hows the quality? How do they compare performance wise to the eddy rpms or the stealth heads?

My dad bought some for his 440 a few months ago the quality looks good have not run them yet. price was great but offset rockers are required which jacks the price up and the exhaust ports are raised.

pretty sure those are a direct copy of the eddy victors.

A friend of mine got a set with cnc advertized flow numbers found out they sell them with different valves than what are used in flow chart and not very good valve job .He put in edlebrock valves smaller diameter and new valve job good flow numbers now.
flow chart was with edlebrock valves larger valve.He will be running them next weekend he had eddies on ran 9.69 best .Maybe buy them bare and cnc'd .
I need to get the new numbers
