Erik,

Thanks... regarding the disty I did not use the o-rings that came with the dist as the ledges they mate with in the block were not chamfered, I checked with MSD about this as their instruction manual was confusing on this point and they said not to use the o-rings and everything will be fine. As for height, I think the dist is just a hair taller and a slightly thicker gasket would solve my problem. I'll probably hold off on all this until I decide whether I'm replacing the intake (likely).

Saxman, the slot you are seeing in the dist hole is the drive shaft for the oil pump... I ran into the same problem you did dropping a new disty where that slot didn't align with the bottom of the dist gear. You can rotate the shaft with long fat screwdriver (I think they recommend spinning it clockwise only) or if you want to get fancy, you can use an oil pump primer which is, in essence a glorified long fat screwdriver
