So I've decided do go for some gt40ps. Based on the research ive done it seems like the most reliable/cheapest head to worl my daily driver fox into the 12s as I build up the supporting mods and the rest of the car. My question now is wheres the best place to get them? Ive called the junkyards in my local area and explorers/mountaineers of the right years are hard to find with the heads still on them and in decent shape. Ive got a buddy tgat works at a machine shop and he said that they dont even really want to mess with some old gt40 stuff and it would be abput $400 to have them looked over, decked, and valves done. With that being said i dont really want to deal with used junkyard parts and im leaning towards getting the refurbished gt40ps off lmr for 650 to save the headache and ill know theyll work. The problem is that they sell the heads with springs only rated to handle the stock HO cam. With better springs it would be 800-850 for P-heads which seems like alot so id like to hear some second opinions befpre i take that approach
