1pc Seal vs. 2pc Seal
I have a question about the blocks on these 2 setups. If I am building a motor from scratch, is the only difference in parts between these 2 blocks the rear main? What I mean is, if you already have a 87-on motor and you replace the intake, you must use an intake from that era due to the inner intake bolts because the heads require it, but if you use a block from 87-on and heads from an earlier setup and the intake, then you should be good, right? The block itself isn't different from the earlier blocks, right, except for the LT-1 blocks, but I am talking about just a standard 87-on block. I have AFR 195 heads, but they were bought for an earlier block, but if I build a motor from the ground up, I should be able to use earlier heads/intake on a 87-later block, right? Thanks.
