My new daily driver. 1984 dodge rampage

At this point check the bottom end. At the plymouth dealer i worked at in the late 80s we would pull the pan and oil pump, knock the pistons out, dingle ball hone the block and re ring it, and put new rod bearings and oil pump in. Poor mans overhaul. Block and crank stay in the car.

Also theres 2 small oil galley plugs in the head, one at either end. this is where the head is bored straight through for oiling to the lifters. I tapped mine for hex key pipe plugs at either end, because when the press in plugs are pulled out of the head for cleaning, new ones dont fit as tightly. If it pops out it makes a big ole mess.

Later 11mm head will fit your year if you need to get another one, bolt holes are bigger. I actually have about 6 good ones if you need one we may be able to work something out. The 10mm head has to get reamed to fit the 11mm block.

I typically assemble intake and exhaust to the head before dropping it on the block as an assembly. Turn 2 of your old headbolts into rounded top dowels with a screwdriver slot, put these into place first. this guides the head onto the block so you dont slide it around and scratch the mating surface on the locating dowels, then just thread them out when you get a few headbolts in.

10mm head has the "bathtub" style combustion chambers. The 11mm went to a swirl port wedge style chamber. A bit better for performance. If you shave a bunch to bring up compression, mopar performance makes a timing belt with 1 less tooth for that purpose. Id recommend the 11mm swirl port head over the bathtub head if you decide to mill it for compression.
