swapping to 91-92 P&C's on an 87
Has anyone 'upgraded' their pre '91 3.3L by swapping to the '91-92 all finned P&C set? If so, any modifications needed on the tins on the cylinders? I'm looking at a new set of these that are being sold almost too cheap to pass on. I've heard that they'll run a bit cooler than the half-finned originals, but I wasn't sure if they are a 'bolt-in' upgrade or if there's more to the picture....
