A member here did a write up (RAMM maybe?) If i remember right they don't flow as well as stock magnum heads, and don't respond the same to the standard tweeks, and very rough casting.
Good memory George--If those are the same as the ones I used in that build then they aren't even close to EQ in terms of casting quality or flow. In all fairness the customer that received that engine LOVES it and they are holding up excellent. Be prepared to grind if you want EQ like performance. J.Rob
