[QUOTE="XFIRE82, post: 144233, member: 2292"] bearings look nice so I see no problem there either. the extra gap can't hurt and like you say is some added insurance. Have you got the heads apart ? what are the valves like for being smooth surface ? I'm no expert, but long ago when I built my '67 396 .030 over, 12.5 TRW's , I put each valve in the drill press and used emery cloth and oil and polished the head smooth on both sides, then ground the face 1/2 degree less than the seat. Cam was hydraulic, racing hyd lifters, lift 500 int / 505 exh 308/328 duration . Guys told me it will never idle under a 1000. Well is ran super nice at 650 rpm . Nice work, great pictures. uhhh, I think you need more engine stands....:Biggrin:... [/QUOTE]
