    so I finally got around to getting another engine, I picked a 420a for a good price, person I bought it from states it has about 150k, and may need head gasket, engine looks like a 420a with 150k that needs a head gasket, so will see hopefully it is not a pandoras box cituation, I am having a hard time finding a mech who can do help me check the 'new' engine and tell me what it might need be done, I dont have the real estate to break down an engine at the momet.

    Well I can tell you without looking. If it has 150k, you'll want it bored .020" over and honed. Pistons to match the new cylinder size and rings. Crank polished and oversized rod bearings, maybe also main bearings. You may be able to skip on that but check it with a mic to be sure. Get the head pressure checked and surfaced. Get the block surfaced too if you're going to install an MLS gasket. Also get new injector o-rings. Engine fires are not fun.

    A new water pump and oil pump is a good idea as well. New timing belt. New tensioner pulley. Use assembly lube on all the new bearings.

    Need help, I'm here.
