Thanks guys for the reply and pointing me to the valve float
So I need to change Comp 918 to Pac 1518 ? what about aftermarket rocker arms ?? Do they help the stable in the higher RPMs ?

I would swap over to the Pac 1518's w/o a doubt. The Comp 918's have a terrible rap sheet and are well known for breaking.

Nice results OP! I have always been a big cam fiend (had an amazing tuner) but your setup rocks and is similar to what I was going to replicate with my GTO before I sold it.

And shame on Comp and their now cheap *** springs...

With drivetrain losses of 40 to 50 hp you may around 470 hp or so at the crank. Thanks for the post, I'm considering a cam like this for my 2000 Z28 A4.
