Yep. I'd say!

Happy to be of some assitance there Markus! We'll get that thing back together in no time. Good option going for the LS6 springs on the re-install too. Nice little upgrade to prevent the further "normal" valve float that so many of these engines have with the regular LS1 springs still in them.

The added spring rate might also help get that valve back up there faster in the event of a mis-shift at some future point it time. I have a mind to take my stuff apart just to check my pushrods and see if everything is still okay.

Bah.. cam time next spring anyhow.

Bro-if your going to plan any mods in the future-just spend the dough and get some good springs now. The LS6 springs are good but they are marginal at best with any aftermarket cams. In the long run you'll be saving money.

Guess I should update this...

Result was 5 bent intake valves and 1 bent exhaust valve.

Oddly all the cylinders except the one tested fine on the compression test...
