MRE roller rockers on Trick Flow heads

The MRE rockers have 900 miles on them......

Concerning the rocker geometry, many engine builders like the mid-lift layout where the rocker arm roller is at the same position on the valve stem with valve closed and valve max lift. I noticed Jesel recommended their rockers be about 0.10 inch below mid-lift so there would be less roller movement across the valve stem as the valve approached full valve lift. Thus the TrickFlow as-is rocker shaft location with MRE rockers appears to be somewhat the Jesel method.

Not trying to start something. On another forum I was told there are as many opinions of rocker geometry as there are members on the forum.

I'm not trying to start something either. I'm trying to stop something, namely the destruction of Mopar valvetrain parts, which always take something else with them. There is a lot to be lost if the valvetrain isn't right, whether the engine fails or not.

Everyone is entitled to their own opinions, but not their own facts. You're not running Jesels, and the recommendations are understandable for engines running 900"+ lifts and 1000lbs + spring pressures with titanium valves and tiny stem diameters. That kind of side loading will flex the small soft stems, and risk failure. So instead, guys throw away their valve springs every 20 passes as a tradeoff for not breaking something else in the valvetrain. Still, many engine builders don't use that recommendation. The NASCAR guys might use Jesel rockers, but they don't set up their geometry that way. The valvetrain guy at Sonny's doesn't set up their ProMod motors that way. How do I know? I have a few inside sources who have confirmed this.

The Trick Flow heads, or any other heads for that matter, don't have the stands positioned for the "Jesel Method" regardless of the rocker used. Valve lift plays a role as well, so your combo just happens to be about .100" low. It would be different for a different combination. Regardless, it isn't right unless you make it right.

You have 900 miles on your rockers and everything looks great. A man once hit a big rock with a sledge hammer 100 times and the rock looked perfect. At 101......... well, you get the idea.
