Bare EQ Magnum heads vs. machining stock Magnums?

Alright sounds good, I already have a set of the Hughes retainers and springs #1110 springs from my "old" heads. These heads I bought from a FABO member about 7 years ago and they were obviously reconditioned to some extent, they weren't just dirty junkyard heads someone pulled and shipped; I'd imagine the valves should be in decent shape.

So at the minimum I'd probably be looking at the cost of the bare EQ heads, plus a valve job, valve guide reaming, and prepping the valves themselves? I'm not gonna pay for pocket porting on these since they flow so much better OOTB...

The guides should be checked and probably only bushed if needed, but yea the valves will need done for sure.
Nice that you already have the springs and retainers.

The mag I have now had around 90k on it and looked really good inside, but man o man were the exhaust valves trashed.
I could turn them 180 degrees and see light around the seats they were so bad.
Besides the crack on all four corner cylinders that was the decision maker for getting the EQ's.
