IIRC,i thought I read to use the 3100 GM spring with the 2.2 retainers also

IIRC I talked to patrick about that when he sugested the comp 901-16 spring for my pre-mag roller set up

and the GM 3100 for a mag head





I just went back through my bookmarks from the other day when I was searching info on springs for magnum engines and patrick/hotroddave did say that you have to use the 3100 retainers with the 3100 springs. He mentioned in one thread that they are the same as the LS1 springs apparently. 2.2/2.5 springs go with the mopar springs
