Selling a pair of PRC heads less than 10k miles, took to machine shop to have heads looked at. Heads are in great condition, no problems. Only reason why im selling, going to 421 CU build and cannot use heads, too much compression.

Asking 950 shipped, if using paypal add 3% fee. If you want pics sent, please send me a PM.

Thanks

What kind of HP was your car running with these. I looked on the TSP web site and couldnt find these heads. What size intake runners, cc, valves etc?

Who milled the heads? did the ycome like that from TSP? I know TSp can do some thing with the heads like resessing the valves to help with piston to valve clearance on teh 59cc heads.
