I am considering building a N/A 427 using a wet sump system and installing it in a 99 C5. Will the stock covers from my LS1 work? Do I need an LS6 valley cover?

Any other suggestions?

Thanks

The valley cover for the LS6 pcv might be a better option anyway. I prefer it over the old style LS1 valley cover just for the better PCV upgrade. LS2 timing set would suffice for this application as well.

+1... if you have to do it go ahead and go with ls6 valley cover..

ls2 timing chain can take a good bit..

LS2 timing set was good enough for the C5-R. I think it will work nicely.
A double roller is just like putting seatbelts on your couch. you won't need that "added insurance" in other words. Plus you have to do some shimming and it is one more thing to mess with when trying to button up the front of the motor.
