Are these Hemi rockers somehow marked as delivered (like a crane rocker for example) or is it up to the racer to determine the actual ratio? And was 1 or all 16 out of spec?
Are modern Hemi's more exact in the RR or are they like engines of yesterday, all over the board and you must sort through 100 to get the 16 you need?
And I would bet my last dollar Teuton had the correct cam lift as measured at the valve.

Unless I missed something Jeff is running the 360 LA Combo...
Right now other than a $4000 Set 0f Jessel contraption there are no aftermarket rockers. Supposedly one is from someone but my brain is too tired the think of it, I think a steel would be killer, the powdered metal is too brittle if it gets scored. A nice set of forged would do the trick.
But Jeff has a 360 , unless like I said I am mistaken and they changed it.
