Valve guides.. FINALLY!

Finally got the valve guides all in.. not a hard job, but had to make a few things.
Fist, the exhaust valves on the 58 235 are at a 16deg angle off vertical...so that means making a wedge to align the hole with the press:
Then I needed to make a seating guide. This was 3/4ths inch black pipe on the lathe to cut off the threads (square) and then move up 7/8ths an inch to make another cut for the proper height of the exhaust valves:
The intake valves are set 15/16ths so that means a 1/2inch ID flat washer to make up the last 1/16th of an inch:
So here is the nitty gritty: An exhaust valve on the fixture, with the spacer in place to stop the ram when the proper valve guide height was set of 7/8ths of an inch:
And here's the intake valve with the washer set to 15/16th of an inch:
Last thing to do was ream the valve guides to .343 with a hand reamer (I got it online, about $40).
Tomorrow I wash the head, lap the valve seats and check the seal. If they are good enough I will install the valve train, if they are off the head will have to go to the shop to have the valve seats cut true to the valve guides.. not super expensive, but will take a few days to get done.
