Honest answer I do not know, I wish the Guy I purchase the MID/LU kept the damage Block I was looking forward to use it as a benchmark since the history of my power head is not known. Per the machine shop its stock, but then again he told me the block did not need decking!

All of the V4 loopers have the bridgeport exhaust IIRC, the V-6's are the ones that changed in 88 and then in 92 added the finger ports. The only real change in the V-4's was in 88 going to larger 3.625 bore from the 3.5" bore of earlier years. And remember NYMACK, I'm not that far away and I have a pretty intimate knowledge of the V-4 loopers.
