l92 on 3.95 bore (ls1)

Has anyone actually notched the block to make these work?

Im considering taking the plunge.

Wondering how bad the valve shrouding on the exhaust would hamper power.

why not just have some smaller seats installed and run 2.08 valves installed. much easier than notching a block.

It's the Exhaust Valve that is the one that's close..not the Intake Valve..

I thought the LS1 was a 3.89 Bore?
