GE 60 vs. GE 80
 
I am thinking about stepping my cams from GE 60 to GE 80
How much will the valve to piston clearance change?
How about deck height?

Ask John (Camgrinder) he will know and I would trust his opinion.

The GE80 cams require about 1.2mm more room on the intake side and about 1mm more on the exhaust side. The 80 cam has added duration and a 2 degree closer lobe center than the 60 cam, both changes will put the valves closer to the pistons.
An increase in compression ratio is wise with this type of change.
