Roller rocker hitting aluminum head???

Budgetmoparman said
Anyone else ever have an issue with aluminum roller rockers rubbing on the pedestal on Edelbrock aluminum heads? The rockers are 440 source's roller rockers, heads are Edelbrock RPM. Still doing mock up so I only have one head on so far but the rocker for the exhaust on the #7 cylinder is rubbing against the mounting pedestal. The roller is centered on the valve stem so I don't think I should shim it over more. I'm thinking the pedestal should be machined a little more?

There is always going to be some adjustments/modifications that need to be made because of tolerance issues.
I keep saying, "You have got to be smarter than your cylinder heads." You have already discovered the problem and thought of an excellent solution. Said solution has been seconded below.

Good catch.

I’d just knock that little corner off the head.

Now will come other suggestions, as always happens, beyond what you have asked. If all you want is for that rocker to clear, you already have your answer.
