Hello all, I have exhausted my searching, and have found most of my answers however I have a few that remain unanswered. My story goes like this, I have a stock 5.0 block, stock everything. It is now in a 64' Falcon where I decided to pull GT40 intake u/l, heads, and injectors from a 96 Explorer. I had the heads milled .030, and got the correct push rods, I just don't want a spring to stay up as P-to-V clearance will be tighter, so spring pressure is of some concern to me. I am running a stock HO cam, and I want to upgrade to roller rockers eventually, but I just don't have the money now.
My problem is... I have read that the stock explorer valve train will not hold up to the stock HO cam, but then I read that the same spring is used in the E7 heads as the GT40 heads. Obviously I want stiffer springs, however the heads are back from the shop after a fresh valve job sporting new hardware. With all that in mind, can I run the stock GT40/E7 springs with the stock HO cam, I'm not drag racing, money is of concern and this is what I have. I have obviously read about the Trick Flow kit from summit for like $120, but is it really worth it? I have read horror stories, but then others say no problems. To my understanding crane sells a kit as well. Can I buy just the springs or do the springs require special retainers as the heads were fitted with new hardware this week and I would hate to pay for something twice, especially if they have the same 50/50 result as the Trick Flow springs.
Sorry for the long explanation/questions, I just want to get my entire story out.
