Angry 1970 351 Cleveland Rocker Arm Settings

I have a highly modified 351C, has a 650 lift cam, solid roller cam, fully ported and poshied heads, running 12.7:1 Compression. My question is what should i set the roller rockers at for space between the valves. Right now I have them all set at .022 but i have heard a lot of diff people tell me all kinds of settings. Just wondering if anyone out here has a good setting. thanks.

I would think that they need to be a little tighter, especially the intakes. What does the cam manufacturer recommend?

I just got emailed from the cam company and they sent all of the specs. The gross valve lift is .679 intake and should be .016 gap and the exhaust gross valve lift was .690 and should be .018 gap. thanks for the response.

I just love it when guys go about finding needed information the correct way. And that must be one heck of a cam manufacturer to send you the needed info on the wekend. Don't see much of that anymore...
