Fcam Valve to Piston Clearance Question

In stalled an Fcam in a '93 stock short block with cast iron GT40 cylinder heads, mocked up the engine without head gaskets and checked valve to piston clearance during overlap, minimum intake valve clearance was .072 inches and exhaust minimum clearance was .125 inches.
Heads and block have never been cut.
Currious to know if anyone else out there has a similar combo and what sort of valve to piston clearances you got.
I was expecting the exhaust clearance to be less than the intake are my results typical.
Just want to confirm I'm on the right track.
 
intake to exhaust clearance ratios are affected by advancing or retarding the cam. ie, you can increase intake and decrease exhaust by changing the cam timing.

I understand that advancing or retarding the cam will impact VtoP clearance and that is part of my concern, are my results typical for a cam installed straight up?
Anybody check VtoP Fcam with GT40's stock block?
