Nothing. We set them up with about 460-470 open pressure on the solid stuff that's .700 lift or better.

Piston to valve clearance is the only thing to have to be careful with.

I have .100" reliefs cut on the intake side of my stock pistons.

A hyd lobe and solid lobe are going to be different because of the ramp profile and valve lash of the solid. A 248 hyd lobe would be equivalent to about a 254-255 solid lobe.

Thanks for the compliment, dyno numbers are cool but Im all about the ET and MPH. That's where you really see what cars are doing and not on xyz dyno.
