A Mustang update

Heads are off, valve train completely out, everything more or less cleaned up. I sourced all new valves and rockers. The original springs are OK, the free height on all of them measures within spec and within a few thousandths from spring to spring. The cam I’m going to use isn’t too aggressive for the pressed-in factory studs or springs, I don’t think. Once I have the heads cleaned up a little more and check the valve guides with a dial indicator, I’ll start lapping and re-assembling the heads.

The block is ready for honing… but I’m holding off a bit until I figure out exactly what I want to do to clean up the water passages. I’d hate to have to replace the cam bearings, so hot tanking or electrolysis is probably not a good option. I may try some Evapo-Rust or CLR and see how well that works.
