I am about to purchase a set of small block chevy EMI manifolds with the aluminum risers. The guy at Eddie marine today said the max cam duration for the aluminum riser's is 230*. If any bigger then that reversion might happen..

So who on the board is running a cam bigger then 230* duration with the EMI aluminum riser's. If its on the ragged edge I can weld extensions on to reduce the chance for reversion. Their is just no room in the budget for the stainless tube riser's.


Thanks guys

Travis
