Yes, made me nervous too
So, i bought manley
i wait them, and new valve guides
it was no sodium filled, bue LS1 stock OEM
i rally race on mountain with some modified subaru and evo... but rarely at full power
i drag race at 7000rpm (who is very high with stroker engine) 200% full power, but longer than 1/4m, but i bought EGT stuff for tune at the max power (egal almost max temp)
but my plan was to test some standing mile race... and perhaps max speed (on a 3 miles track)...
wait and see ^^

For stuff like 3 miles etc....I'd have bought Inconel exhausts.
For all the shorter duration work, even a mile, good quality stainless would be fine.
3 miles full throttle is a LOT !
Make sure the exhaust has a nice fat seat to help get rid of heat

I was not able to find inconel for LS1 size...
Just find for LS3...
Fortunatly, the no limit race is not for tomorow...
On this track (5.8km aka 3.6miles), the Bugatti Veyron af a client just approch 400kmh (aka 248.6mph)
My challenge should be to hit the magic number of 400kmh... or the other magic number of 250mph
But i think i will spend a lot of money in tires and brake system (cannot beat the stock aero brake system and probably the best of carbon ceramic from Bugatti)
So, for for moment, i will be happy with a mile race...
Or with a 10s pass of the 1/4m
Or basiquely with a engine who work fine without burning oïl ^^
I have to check everything is ok before ^^
