Indy/RHS Heads

Mad Dart said
I seen these head a while ago like everyone else. Hughes at first really bad mouthed them. After further investigation they sort of took their words back. I am pretty, sure and Bobby can tell you the straight facts, that you could still run a pretty big cam by changing the valves to the 11/32 like he is for me. My cam is .624 lift and Bobby is leaving .080 room on my set up for clearance. I think with a taller valve and different locks and retainers you could go over .700 lift with these. Bobby could this be a reality??
I talked to Tim at Hughes along with Kevin and they both believe that this casting will put the hurting on the sale of Edelbrock heads, and that the EQ Iron Rams will be used more as a replacement head. If these Heads FULL out will flow 320-340 CFM in the right persons hands, I could see it happening without a doubt.

Louis,
I believe that in time they will hurt the sale of Eddy's, but I don't know if I would use the EQ heads as a replacement head or not, as they'er a good bit larger than the stock castings. I guess if there isn't any other heads available at the time then I would have to use them for that purpose, but for a stock application I would stay as small as possiable for the street.

I think that to get the 320-340 numbers that I mentioned before it would take some serious work and relocating of the pushrods and removing alot of the pushrod pinch. But this would be like Rumble said, if I could get one just to see how far I could go and just do R&D on one. The way that I see it is I could do 4 different things to see how it effects the airflow. Or I could do one port and then fill it back up with putty and reshape it differently and try again.

I did this with combustion chambers a few years back and found 50 cfm's in just the chamber shape. When I was finished with the chamber is was something like 45 cc's but it flowed some serious air. IIRC it flowed 375 on the intake and 280 on the exh. and it was a 906 head. What was so shocking was the fact that the exh. valve looked to be very shrouded but thats what the air flow liked. I was going to do a set of heads like that and weld up the chambers and just never got around to doing it. Then I bought a set of S-6 MW heads and did it to them instead. They ended up flowing 390 and 285 int./exh. @ .700 lift. with 2.14/1.81 valves. The B-1 TS chambers are very similar. I also have a set of these that flow 560 @ 1. and 380 on the exh @ .9 lifts. Sorry for getting off track here. When I start thinking about R&D and changing things around I start to ramble on different thoughts and whats been done in the past.
