Found a small problem..
 

Well, my buddy Mike and I pulled the plugs to find #7 with a touch of rust on it. First sign of a head gasket issue. Did a compression test on the whole motor. 6cyls were all in the 174-176psi range including #7. One cyl was low 180's and one was high 160's. So they were all pretty close. But after pulling the driver head off yesterday, I'm glad I ordered up gaskets and switching to ARP studs from ARP bolts. This is a pic of the #7 cyl. Only one that seemed to have an issue which is a normal LS1 thing due to the intake design. I might be swaping to a single plain Carb style Vic JR or Super Vic in the near future.
