I have a set of the SR (M.W. ports, no extra porting that I know of, they flow 340 at .700 on a super Flow 600 bench)that are on my 518 C.I. pump gas low deck stroker now. The car weighs right at 3450 lbs. with me in it, best so far with the Indy 400-2 intake and Holley 850 D.P.(#4781-7)with a 1.5 phenloic spacer is 10.31 on the brakes and the best MPH the same day off of the brakes was 129.72. I do run a set of T&D rockers that are 1.65 ratio on a .420 lobe lift solid roller cam. That is on Oregon pump gas with the air cleaner and exhaust system on I'm going to switch the intake and carb. to a Indy 400-3 with a 1.5 inch cloverleaf spacer and a Holley 1050 dominator, probally remove the exhaust also to put a set of taller tires on it to hold the "extra power", I hope

Have you given any thought to the 440-1 heads? They should be fine OTB and you would have room for improvement in the future. A lot of people on here run the SR heads and like them,but 98% of them have spent big $$$$ in having them ported.

I've got a pair of SRs on my 11.5:1, .564"/.564" 251/257 flat tappet cam, Indy dual-plane, Holley 850 DP, .055" over 440. I'm happy with the heads, but just know in advance: if you're putting them on an RB block, you're probably going to have to buy a set of super-expensive (but super-nice) TTI step headers made for the SR heads. I believe that Hedman used to also make headers that would work with the SRs. Good luck.

Glad to see this post. I have a set I'am getting ready to put on 500/511 motor (still in the works) trying to decide how far to go with them. I only want to go low tens. I have a friend who has his maxed out MW fully ported they look nice and do the job for him. Did any of you change out springs and retainers?

I had a 451 (.060 over 440)Comp. Cams roller 286/750 with ported&polished 915 heads,12-1 lighten Speed-Pro pistons,D-C Hi-Perf. rods&3.75 crank(mid 80's build) done by some big time Mopar guys.Put a set of OTB 440-1 heads & picked up 100 HP on the dyno.All work & dyno done by the Barnetts. I don't think the SR's or EZ's will do that. I know a few people who run both heads and have put a lot of $$$ into them in port work and they do run good.But they have now invested as much as a set of 440-1's which would be faster cost.
