Trick Flow 190 Heads, hydraulic roller cam, and pushrod angle Question.

Would this not defeat some or all of the advantage of running a proper matched solid cam and lifter set? I mean I have seen the difference in the ramp lengths of HR to SRs being as high as 17*. And as you know, the .008/.006 advertised spec is no where near when the valve actually closes. I understand that running solids on hydros might make them quieter because of the gentle ramps, but in this case the quiet is eating up valuable cylinder pressure. 8 degrees,half the difference, equates to roughly 12psi.
Is my thinking wrong?
What I mean is; just because you can do it, and it works; is it still a good thing to do?


How do you think they came up with “tight lash” solid rollers?

They are HR lobes with SR lifters.

Guys get way to worked up over lash ramps and all that.

Put solids on a HR lobe, lash it at .002 cold and send it.
