I pulled two connecting rod caps off in my 81 back in 97 when I had the heads redone. About the same mileage (broken head stud) Bearings were fine. Replaced the bolts with two new factory stretch bolts on the rods.

Doubt bearings are going to be necessary but there has to be some value in doing it.

My exhaust valves stems were below tolerance.

I did nothing with my Alusil P&C's except clean them up and check bores, ring land gap, ring end gap. They were fine. Bores were maybe a half thousandth out of round.

Consider replacing the lower studs. Not sure if you can mix and match studs. I put raceware in top and bottom but they were "only" $500 back then. $375 for bolts and I got the fancy nut set as well.

I do remember they flycut the top of the heads six thousandths for a good seal seat. They stamped the machining dimension into the head which I though was pretty cool. I did some volumetric calcs and it took my 9:3 up to 9.5. An easy one or two hp. :-)
