    I have a 69 RR with P&P 452 88cc heads. Looking for a winter project, has anyone tried/run Indy EZ, Trick Flow C00 or Edelbrock Performer RPM heads? Any other mfg you would recommend? My 440 has .505 lift, 510 HP, 580 ft-lb, 4 speed

    Having run all three, the Trick Flow is by far the most refined of the bunch. It will however raise your present compression ratio one full point. And it is critical that you check the valve guide clearance on the Trick Flow heads as I've found them to be too tight. I've had to hone the guides on every Trick Flow head I've had in the shop. They all need to be prepared by a good cylinder head shop before being used.

    Do you think -10cc will increase the compression one full point? I will have whatever head I buy checked before installing

    The compression ratio is a pretty simple calculation which I did before I posted my reply. So, I don't think so, I know so.

    I did the Edelbrock E-Street heads on my Valiant. They have an 84cc which is close to stock and a 75cc which I used with a thin gasket to pick up more than 1 compression point I started with a low compression 440 so I'm around 9.8 to 1

    A suggestion with what I’ve had decent luck with. Bargain 440 Source heads with a cnc workover by KG Engines in Kansas, OH. KG has a display at almost all MOPAR events I’ve attended and are the Real (!) deal!:thumbsup::beep:

    Yes 440 Source Stealth heads are very good too.

    Call Bruce Toth google the name if you need to! I had a set of stealth heads and they had to be clearenced for the oush rods and then i overheated once and they warped enough to cause exhaust gasses in the coolant. Bruces heads come already ported and clearenced etc for the same price shipped! Toth perfornance in Penn call him dont waste your money on stealths trick flows would be the next best.
