Need Advice On Magnum Crate Engine

Couple thoughts: heads were probably only milled few thou, mopar wasn't known for going nuts on that because they used stock valvetrain. You could put in stock valvetrain and feel play on pushrods as you tighten it down. Otherwise get adjustable rockers then adjust them with stock rods and don't have to pay pro builder. Second advertise the intake for trade to dual plane rather than weld up good FI intake.
