Ported Slant 6 head

Did frank blend the bigger valve seats in?
If it had to be dun he did for the bigger valves, all I asked for is a all new ready to bolt on very little shaved (40thousants) bigger valve head and I did not want real heavy springs because of my application :happy1: But that was about 18 months ago and the head I am running original from 1966 has not gave me any problems at all yet so it will not be coming off any time soon :happy1: I may be wrong but I think he had the head cut and is seated with furd valves, but I may be wrong on that becouse we talked in person about using a furd valve in these /6'es 1wild&crazyguy.
