They popularized the "real Chrysler" cam with lobes that use the 0.904 lifter to advantage. Some members have had extremely good luck with them. Most of the complaints have been when someone from the board caught someone at Hughes on a bad day. But they do know their Mopars. R.

Yes they do and so do the BAE fat heads. But these are both billet alcohol heads not made for street use. NRE X1 H20 heads have water passages. My mate has a set at his shop at the moment that are going on a burnout car.

When I get down there and pick them up I will get them flowed. They claim 480cfm and I will have $3400 into them..I only need 440cfm or so to hit my goal. As for the eddy heads, got to see a set Saturday, they don't even clear the rivets on the Cometec gaskets...Keep them! Last edited by Dragula; 01/28/15 10:10 PM.

Yeah Cometic has not figured out that the brass rivets that hold the MLS gasket layers together should be moved farther out. It's just one of those things you have to look for that the rivet isn't caught between the head and block. No biggie, I just remove the offending rivet and move on.

That's a pretty poor reason to not use a set of heads.

Tim If you use the old formula of 2 HP per CFM that is 140 HP, correct I've seen that on swapping wedge heads with the same combustion volume on the same short block with no other changes. Actually on the higher compression motors that I did the same swap on with the same heads, Indy SR M.W. compared to 440-1 CNC ported with 30 CFM differences the higher compression motor made more HP per CFM than did the lower pump gas compression ratio motor, not the same short block on both motors either IHTHs Mr.Cab Racing and winning with Mopars since 1964.
