Well, after much thought heres what I've decided to do. I'm gonna ditch the +.050 locks in favor of standard locks. This gives me plenty of valve tip to work with. I'll machine the guides down a bit to give me the necessary retainer to guide clearance, and live with the slightly increased seat pressure( up from 130# @ 1.80" installed height to 145# @ 1.75" installed height). I'll still be safe from coil bind and my open pressure will be in line(342# @ 1.20") A guide cutter and new seals is a helluve lot cheaper than the new valve order I cancelled. That and I had just gotten a valve job done on them a month or so ago. The proverbial "fly in the ointment" was the +.050 locks. They just won't work with .25" valve tips and self aligning rocker arms. Dare I ask, anyone see issues with this or does it seem the logical thing to do?
BTW Cobalt, the stamped rockers were contacting locks/ retainers also
