I was talk into buying a new set of the Speed Master(AKA Pro Form) BB Eddy Victor clone heads (part # PCE281.2142) with CNC porting with 325 CC intake ports. I ASSUMED they would be M.W. intake port size, not so The intake ports are way wider in the pushrod pinch area than any stock Mopar heads I've seen and they have 2.200 intake valves along with 1.81 exhaust valves with soft CNC combustion chambers My question is are any of you on here using them? If so what are your thoughts on them Thanks in advance on ALL comments

I don't have any flow sheets or claimed or actual flow numbers on them The pushrod holes need work, enlarging, to make them clear the 3/8 diameter pushrods I'm using to check P to V clearances. I put a set of mismatched rocker arms together using a set of Hughes 1.6 ratio offset extruded aluminum intake rocker arms for the Eddy Victor heads that i have and another set of CAT brand 1.7 ratio exhaust roller rocker arms. I need to grind the pushrod holes to clear the push rods and recheck the P to V clearances as well as ratio at the valve retainers I ordered a Speed Master brand 1.5 ratio roller rocker kit with shafts and hold downs, I'll see how they fit and what ratio they check out to be I'm planning on dyno testing this 505 C.I. pump gas motor with these heads with a Team G intake with several different DP carbs. I have and jet the carbs for best HP

I have two RB Weiand intakes that look alike, one is marked Team G and the other one isn't. I may have a Eddy 440 RPM also I am not building this motor for me to use as I have 4 other complete stroker motors and two cars. I bought these heads to try not realizing that Dwayne had already tested them I'm currently planning on dyno testing this one and one other similar motor at the same facility the next day, it has a tight (105) LSA solid roller Crower cam I bought from a member on here several years ago, it has a decent set of 440-1 heads on so we will see how these two motors compare. I'm planning on testing three different carbs. on both motors to see which one works the best and how power differences there are Both motors are 440 with 4.250 stroke and right at 11 to 1 compression ratio, I'll use the same pump fuel in both motors
