Cam phase suggestion advice

Ok so I found out why the P/V clearance is not right! The rockers were preloading the valves. Which was somewhat strange because I took a couple of the old hydraulic lifters and welded them solid, I put the factory head gasket back on and tightened down the rocker shaft, I thought I could feel a hint of lash and could spin the pushrods (in hindsight the light checking springs gave me a false sense of zero lash!), set the indicator at zero on the intake valve retainer then backed off the rocker shaft bolts and bingo...the valves were hanging open. I don't have any adjustable rocker arms so I shimmed up the rocker shaft to get a few thou of valve tip clearance with the lifters on the cam base. Now the indicator reads .095 clearance on the intake at the tightest spot which appears to be right at TDC and the exhaust has about .145 clearance @ 2 degrees BTDC. So next time I'll leave the bottle of wine alone until after I get out of the garage, and I'll make sure I have a set of adjustable rockers! It's a shame too because I spent a few hours whipping up a couple of nice valve pocket cutters.
So yes this Lunati #702 voodoo cam can be run with a mid eighties 318 with eyebrowless flat top pistons, however this was checked with heads that have been cut .015 and the used factory head gasket (.040 thick) snugged down . Shortly I'll be getting the block decked (around .010) and will be using the .028 head gaskets so that will be bringing the intake valve probably a little too close for comfort. I'll recheck the set up tomorrow without the head gasket to simulate the final setup and let you folks know!
