Message	The NA heads are 30P castings vs the 40P castings for the TT. It has been shown that the castings are similar but the exhaust valves are different between the TT and NA in that the TT heads use inconel exhaust valves. Since you have removed both heads to inspect the valves you should have the heads serviced. Checked for flatness and valves checked for play and seal. Essentially you should get a valve job done. The guides will not have to be replaced unless they are out of spec. The heads will come back clean, valves lapped for a nice tight seal, and new valves stem seals at the very least.
