Last night while checking out the aignment of the oil passages on my timing cover to the ones on the block, I also took a look at the coolant passages. has anyone noticed a pretty major mis-match between the two? The holes in the block are much smaller than the passages in the timing cover. since I had the die grinder out already I opened them up a little and radiused the edges out close to the gasket line. Not sure if it make a difference but figured I'd ask anyway.
