Agreed, Archie does excellent work. The loaded heads are for a mildly warmed up 318 (@318willrun, ya gotcher ears on?) that will go in an early A. For that, I suspect you're right - give them an inspection and if they look decent run them. The bare heads are going on the 340 in the Dart, and they will be built when the time comes.
Mine may very well end up on a 318 themselves !!
