hi guys, I have a semi weird question. I've been building a 302 for my car, but I need to move the car from where it is, and it needs to be running. Ive been waiting for the Machine shop to finish my heads but they will be a while. Right now the block still has the factory 77 302 heads on it. I put the cam and new valve train in on the old heads, but if I just toghten the nuts down to the positive stop I will have too much preload. Can I get away with using poly locks for now just to break in the cam and drive it over to where it has to be stored temporarily? Then once the new heads are ready and I can bring it to my house swap them over?
