Hello Maverick/Comet Lovers! I'm hailing from El Paso Texas. I am looking for help with the DOOE casting heads for a 302 or 351 Winsor setup. My left head cracked through the exhaust side and here in these junkyards and such I cant find that head anymore. Anybody have the DOoE casting heads lying around a shop? Please help me!! I want to keep on Strutting with my GT Comet around the road but it smokes white only on the cracked head. A sealer has minimized the smoke, but Im losing power and smoke still escapes.
