We measured P to V clearance today (without .028 head gasket) using both the clay and dial indicator method. Dial indicator results (without head gasket and with test springs) were as follows: Exhaust: 15*=104, 10*=88, 5*=90. Intake: 5*=75, 10*=70, 15*=76. Jerry Clayton was dead on, as 10* showed least amount of clearance. Claying the pistons (without h.gasket and with 1.550 springs), I split the clay in two and measured the thinnest area I saw on intake and exhaust. Results i got were around 0.160 on exhaust and 0.140 on intake. First time I've ever measured P to V but was a good experience and hope I did things right! As to radial clearance, eyeballing it, I saw no alarm bells (maybe someone else can confirm from pic). So I'm pleased with the results. Did have an issue with the pushrods I ordered (and posted a thread on the SBC section). I wanted to use 3/8 rods i ordered but found they would only work on exhaust valley, not intake. Would have helped if I'd read the doc that came with heads which stated, 'must use 5/16 rods.'
