So I have a set of GT40 heads in the shop I am reconditioning, came off a Ford Exploder. The EXH valves have roto caps and different springs than the INT valves. Keeper grooves are lower on EXH valves than INT.

I was planning on new springs anyway but the set/installed height is different on the INT and EXH.

What is the suggest remedy for this situation? Going to the shop now and will post findings and measurements later today.

Anyone have any experience with this?
