Thanks to all for the great responses to my oil pressure issue. With all of
your responses I have a nice progression of items to check from least to most
invasive.
To answer several questions you have asked for clarification, here are my
answers.
Spin on oil filter with Wix 51516 filter.
No oil cooler.
Engine block was magnafluxed.
Goodparts roller rockers with screw in tact.
New oil pump replaced somewhat new pump that had scoring. I did not check the
clearances of the pump prior or during installation.
No cam shaft bearings.
pistons are 40 over with 10.25:1 compression per Kas's measurements in the
prep manual.
I will update the group when I have a chance to investigate further later this
week.
Thanks and I hope to see many of you at Triumphest/VTR!

was relatively new, but we all know that new parts are not the same quality as
the original parts. Perhaps that is your issue? You can check this by putting
a washer under the spring to act as a shim. If your pressure readings go up
then you need a new spring in there.

above statement that the new parts are not always equal in quality to the old
parts, I would suggest swapping the old pump back in and see what happens. I
KNOW that there have been some issues with the new pumps. I don't remember the
particulars, but some people had complete failures with the currently
available pumps. I'm pretty sure I read somewhere (6-Pack Forum maybe) that
blueprinting the oem pumps was actually preferred using the new pumps.
