more info... the heads are 452's and they have already been rebuilt by the previous owner and the engine was never started..... was set up for a .484 lift cam.....

Why not just order them from Engle. They will have the matching spring for that grind.....it's very important to get it right, or you will have all kinds of problems. Depending on what springs have been installed inthe 452's....you could be fine. I'd call engle and ask for the specs on their springs to see if they are close to what you've allready got. You need specs for seat pressure, open pressure,installed height and coilbind. Once you have that info, have a machineist inspect your heads and see what you've got....before spending any money.
