I understand your reasons for running 190 lbs on the seat. I just never heard of that much pressure on a hydraulic lifter. That is good news to me. It gives me confidence in the Morel lifters.

Smitty,
I am propped to run at 5700 rpm. I dont remember off hand what my open pressure is. When I get home, I can look it up.

An alternative source is DRERACING.com.They manufacture shaft rockers.However, especially nice, they will fit the stands to your heads.And if they have your cam and head gasket thickness,help with the push rod diameter,length and fit.In other words;mock up your heads to fit the stands and rockers by using their block(s) and adjustable push rods.They may also suggest 7/16 diameter .120 wall push rods.Some feel the bigger push rod has less deflection,less vibration and serves to reduce roller skating.
