Good for you...sounds like a good motor, and Keith was/is the pioneer with hydraulic rollers.

My 482 arruminum Shelby is running 264/264 duration, 110 separation, .658 lift and has run just fine for the past 10 years at the track, high heat stop/go and anything else thrown at it...no problemos since we went to the old-school solid flat tappet (original solid roller was a bit problematic, but that was back in 2003). Boghosian-built and maintained.

Just to let you know you've got a good safety margin built in.
