94 Mustang GT: Daily Driver Motor: Valve Springs

Update:  I got a package from Flow Tech Induction!  Package included the custom grind cam, new set of lifters and a new set of valve springs.  Forgive me, but I didn't take any pics.

I took the heads over to my buddy's place and we removed the springs / retainers / locks / shims.  After looking at the new valve springs and the specs on them we measured the installed height.  Then we tested the springs to find out if they would need any shimming to have the correct seat pressure at the installed height.  It was really close.  It turns out that we used shims on the intake side, but the exhaust was OK.

There are two different sets of locks that come with the retainers.  one set is for the intake and the other for the exhaust.  When we were done, everything looked great.  We also found that some of the guides were not seated correctly.  This was also corrected.  After seeing the new spring package installed on the heads, and the specs on the cam - I'm pretty excited to make some more progress!

I also received the main and rod bearings, and the piston rings.  Here they are, summit racing part numbers for reference:
Clevite Rod Bearings:  CLE-CB634P
Perfect Circle piston Rings:  PCR-3150036-030
Clevite MS590P main bearings

Next step is to clean all the gasket surfaces on the block, and get the block cleaned up.  Then we will correct the cylinder walls and give it that nice cross hatching.  At that point, re-assembly can begin!
