I have, put away somewhere, a set of Comp springs that I got for a custom Comp solid roller. The cam had .659-.666 lift They were run for less than an hour---only while running-in the engine on the dyno. You can have 'em for $50 plus shipping if you're interested. I have a set of 10 degree TI retainers as well, and they may all be in the same place. We can talk if you want. I'll try to dig them out this coming weekend if you like. Let me know!
