Roller rocker hitting aluminum head???
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?
