Will update the post when I hear from the machine shop. Last time I had one look like that it had a crack under the exaust valve.
Just to update, machine shop confirms cracked valve seats as suspected. seems to be a possible casting problem with the 305 heads
Wow, kudos to you Bt Doctur, I live in NJ and sadly did not think that there were many honest people left in the Great Garden State but I definitely count you in as an extraordinarily rare example of the sorely missed and near extinct "Good honest solid Guys" Thank you for restoring my faith in New Jerseyians and human kind as a whole!!
