Valve spring upgrade
What valve springs are you using that's good for around a .520 lift and fits in the stock OE pocket (no machining) for my 93 5.0 HO? I called CJ ponies and the rep gave me pt#986-16 which I think is Compcams #. He stated it does not require machining of the stock head spring pockets but their description reads some machining required. He also asked me if it was a 289. Maybe he didn't hear the year model.
