i have basically a complete 86 style setup right now (with ported/o-ringed 86 cylinder and milled 86 head), and my original crankshaft bearing let loose. now i need to decide which crank/piston setup i want to use to rebuild this thing. let me hear your opinions, i decided i want to definetely go with a oem crank 87-89 crank, but am finding myself torn between using the 86 piston with a spacer or using a later piston with no spacer. how much more power is found in the spacer setup? i also need to get a idea what kinda bearing,gaskets, etc i should purchase so i can do this whole thing at once. also the stock head was nicked up with the engine failure, so i need to purchase a new stock head, when i get the new head on the engine i am gonna do a compression test, how much should i take off the head to get say 5 more pounds of compression?
