Trick Flow Heads: Conflicting Info on Mechanical Roller Spring Pressure

PAC Racing 1238x set at 1.880 gave me 236 on the seat and 626 open at .668 lift. I shift at 6800. Well, my shift light is set at 6800. It'll wind way up if I'm not ready for it.

I'm looking at the actual Compu-Spring printout done on my heads. so....not guessing. MY Guru says advertised pressures are always over stated.

And Turk's right about the lifters, especially for your intended use. .800 wheel is a must! BAMM, baby!
