Edelbrock / RHS heads, or go BIG block and put it to bed!

Bull puckies! lol
I run OOTB RPMs with valve jobs corrected and gasket matched on my strokers and they make 450-490hp depending on the combo. That's about 240-245 on a street cammed engine (.497 @ the retainer) by the numbers. And that's more than one set of them over years. So I can't agree with that.
That being said - The comparison is not apples to apples. The RHS are ready to bolt on for $1350+S7H from Brian. They are purchased as bare castings so if you buy them, your shop may get more for the work or get worse results. RPMs come assembled but IMO are not in any condition to be run OOTB. They need the valve job fixed, special head bolts, the special Fel Pro head gaskets, and possibly upgraded springs which brings the cost to get them on the engine and running up to around $2K plus springs. RPMs are lighter and have more potential than the RHS heads. But that costs.
In this particular instance, I think Brain's heads are the better choice. Again assuming the engine is healthy and the issues it has are tuning/setup. I still don't believe it is but that's of no consequence.

What part of at .400 didn't get through... In essence that's the real port #'s he's going to access with that cam and bad pushrod angles.

Even at .500 or as you mention, .497 at retainer, the ede doesn't come close to the 260-270 numbers the rhs head goes... The RHS is consistently ahead of the ede at all lifts above 300 by a solid 20 cfm. Those are from the same bench, so it's apples to apples.

The RHS does the 450-500+ with NO PORT WORK whatsoever on strokers! No port matching, no guide slimming, no extra work except how Brian does them up blending the bottom cut. I really wish Brian had more time to do a back to back on these things, his RHS set up and an OOTB ede configuration (even with the VJ corrected).

I do agree with the comment that the RHS are a better choice, better parts, better machine work.

I just think it's stupid to spend more money for a product, that's inferior in design, only because it's aluminum. Pick your parts, spend your money where you see fit. I know I'll NEVER buy another set of ede's unless they are a smoking deal and I want somewhere in the 550-600hp range. Other than that, there are MUCH better choices out there.

It's all good.
