I have a set of Edelbrocks on my daughters car and now i want to go with the RHS, seems to me that alum heads are not good with 10.5 comp motor they dont build enough heat i am now going to put in a 195 themostat, see if that helps
Most guys would love for they're cars to run so cool they HAVE to run hotter t-stats!! Let me tell you...eddy heads can be made to work very well. If you already have them, I'd invest in some porting to pick power up if that's what your looking for.
To me, the RHS heads are best if your starting from scratch or replacing OE heads. I've had one customer go from eddy heads to RHS heads with no other changes and really liked the difference but I don't go out of my way to talk people out of the eddy heads and into the RHS.
