What rockers to use on trickflow 190's

If the rockers hit the springs, you need to fix the rocker geometry. You can run at least a 1.550 spring with the geometry correct before you need to offset the shafts.

Harland Sharps wont clear any bigger than a 1.50 spring on Eddie Heads. That per Dwayne Porter@ PRH
I know i have 1.46 trick flow springs on my eddies with HS rockers. Dwayne specc’ed them for me. They work with a fairly aggressive flat tappet i use very nicely.

They will clear if the rocker arm geometry is right. Everyone knows, or should know that the shafts are too low and too close to the valve. Longer valves, longer rockers, more lift are just a few things that make it worse.

There is plenty of room for a 1.550 spring with any rocker IF the shafts are in the right place. After that, you have to mill the stands and use offset shafts and stands

I would think that a good first move would be to check with B3 no BS
longer rockers all good with the shafts in the right place
allows more pushrod room (or more ratio

I checked with him... Mike is a great guy. if anyone is considering these heads maybe drop him a line because he has some pricing on a package deal

Has anybody checked the real ratio on the PRW rockers lately, i have an older set of the stainless 1.6 advertised, but they are nowhere near that ratio.

Mine are over 1.6 with checking springs, and right on the money with valve springs on them.
