I'd talk w/ Dwayne Porter before you jump ship and build a wedge. He spec'd my cam and springs. No issues here and we're using "similar" setups.
I have DLI roller rockers, MP shafts, and MP stands on MP heads.
You obviously have something wrong...whether it's the cam/spring combo or an oiling issue, I don't know.
Well, my thinking is, if we test the other intake springs and find that they have fatigued as well, its an oiling issue for sure, which is what I am pretty sure it is...Last time, I broke 4 of them, all intake springs. We will look at the oil feed holes in the rockers and see what they look like with the valve covers off. The only fix will be the RB rockers....And I already have a cam on order with a milder ramp rate...
I was on Indy's Facebook page, man those Predator engines make some steam....
