Ls1 heads need help? i just bought a ls1 out of a 98 z28 are the heads 853 or 241s an also if the motor supposely has 35to40k on it should the rear main seal be leaking ?
First off look at the valve covers and are the bolts in the center or on the perimeter? If they are in the perimeter then you an 853 head for sure. 853s also came with center bolt valve covers as well. The only true way to tell is look on the head for the number. There is no way you have 241s unless someone swapped them on to the block.

241s really are not that good of heads Advice is free mistakes tend to cost after a while hence my mistake hopefully will help you save money.
