These have been machined to fit 2.190 intake valves and 1.650 exhaust valves. New 11/32 bronze valve guides and Viton valve seals. Spring seats were cut (O.E. diameter) to fit the beehive springs which are using spring seats that fit the 5/8 (.625) guides. No work has been done to the heads to take advantage of the bigger valve sizes. $500 for the heads without springs, retainers and valves. I plan on using the valves in a different set of heads but I will entertain the idea of selling as a complete package. Buyer will pay shipping from 52342. I would be willing to make a 2 or 3 hour drive to meet someone 1/2 way.
