Im currently converting my LT1 heads to vortec heads and I'm going to bolt them to my Chevy 355 roller motor. I was just wondering if the 1.52 roller rockers from my sbc heads would bolt right on to the LT1 heads and if not, what would i have to do to make them work?
LT1 Heads on an SBC

The LT1 uses tip guided rockers, and all non roller cam SBC's use pushrod guided rockers. There is no way to easily interchange the two except maybe to use pushrod guideplates and screw in studs on the later heads. I would also caution you that LT1 heads have a very different set of coolant passages than the GEN I SBC did and it will be quite difficult to convert one to the other. You would be well advised to just use GEN I heads instead. (The LT1 uses a reverse flow cooling scheme in which the heads are the first recipient of the coolant out of the water pump whereas the block is the primary recipient in a GEN I.)
