I beleive the problem is the retainer to guide clearance because the machine shop did not install the drop in springs required and I can no longer find them.
the car needs the valves adjusted and it should run, but I couldn't figure it out and don't want to screw it up since my valvetrain is so sensitive..

Just for reference, I run the XE268 cam in my Vortec 355.
.477/.480 lift w/ 1.5 rocker. I originally bought an XE274 cam that was .484/.490 but figured that was cutting it too close. Plus the powerband (1600 to 5800) is very good for street use. I also measured and replaced the pushrods and took steps to make sure my valvetrain geometry was good.
Other guys really like the Lunati Voodoo cams. I have heard they run quieter than the XE series but do not have firsthand experience.
