[RICK LAKE]

PANAVIA Steve I have run shelby heads for 10 years with a port and bowl cleanup. The failures have been with rocker shafts. They have ripped the helicoils out of the aluminum heads. I am not running big camshafts or high pressure springs. I removed all the helicoils and replaced them with timecerts. No failures with leaks with CS heads. I have a set of EDELbrocks with a ton of work done to them. They are waiting on my new short block to get done.
KCR and Barry R both sell heads with stage 1,2,3, setups. 1 or 2 would be all you want. The other thing is match the manifold to the heads for better distribution on the air,fuel mixture to each cylinder. Joe Craine does this and the work looks like art after he matches the flows on all the ports. IMO this is worth the extra $300.00-400.00 and he know what to check and fill or repair if needed.
Aluminum saves weight, Iron is more correct for the car. Try e-bay, there was a 428 motor for sale out on Indiania or Ill. The motor was complete. That the heads and you have a spare short block. Rick L.
