Hey guys had a quick question. I'm going from 806 heads to 241 heads on my '98 LS1. I also bought a set of PAC valve springs. The PACs are good to use on stock springs, seats, and retainers I've been told (they're the single beehive ones). But as far as I have seen, there are no seats in my 806 heads and my 241s came bare. Am I going to need seats? And can I reuse the locks and retainers from the 806s? They are in good shape. Thanks!

You can use the Comp Cam #4705-16 seats.

seats are part of the seal on my 241s

Buy a set of the later GM seals, which are one piece seal/seat. This will solve both problems plus these seals cannot come off the guides. SDPC should have the part numbers, if not I may have them somewhere. The later 241 heads came with these from the factory.
