if they are just honed, you will most likely need new piston rings, and to perform the piston ring gap procedure, to make sure the gap matches the factory recommended spec

if the bores are machined, THEN you will need oversize pistons, and those pistons should come with new rings. you will still need to make sure the new rings have the correct gap, according to the piston manufacturers recommended spec.

perfect! thank you so much for the response! I'm taking the block to the shop to get it review. I guess I need to wait till the new oil pump so they can get decked at the same time.

send the oil pump gears out to be WPC treated. Its fairly cheap for small parts.

I highly recommend #WPCALLTHETHINGS

but at the same time, my bill for WPC Treatment on my last engine build was $$$$. Had the cylinder bores, piston rings, crank and main bearings, camshafts, rods, pistons, crankshaft, and oil pump gears done. this engine better last forever.

I'll look into it. I'm not sure if I want to keep this car for much longer, but I do want everything to check out right. I got call from the machine shop today. They could not find anything wrong with the head, valves, valve train was perfect. So not sure where that noise is coming from. It is from the bottom tho. Im tearing the timing cover and oil pan off tomorrow.

Found out what the sound was on this video

A tiny piece from the time cover broke off and was rubbing against the chain.
