I think that I've got Comp Cam lifters, but I bought them about 8 years ago... A quick post WD-40 compression check with my $5 gauge showed a high of 170 PSI on a couple of cylinders, down to a low of 40 and 25 PSI on numbers 7 and 8.
I did try the I-talian tune up just for fun, but I think I'm in for a tear down Monday after work. This thing is still fast even on 6 cylinders, I can hardly wait to see what it's like on all 8! I'll do one more compression test prior to turning bolts to the left, but I'm guessing that there are new rings in my future.....
Thanks,
Jon
