This was when they were on the original owners vehicle. Since then the heads have been gone through and checked, and double checked. Additional

portwork done, to finish the smoothing of the runners, pocket ported, and the valve pocket has been ported to match the enlarged Ferroa valves.

Pics will be up ASAP, will include Cam Sheet, and my receipt for the headwork, as well as heads/cam.


I am only asking for the money I have in these heads/Cam. Not in a hurry to sell.

$1800.
