I believe what he is talking about is, if you give him a head that has been rebuilt with hard seats, they will fall out when he furnace brazes on the adapter.Harlon":2o2xd0u4 said:X,
From what I can tell that is the same builder for this head.
I’m going to buy it either way as the price gets me to far down the road to pass up.
Question though is: in one of the builders posts in that thread it says if the head is machined the bronze holding in the hard seats will melt and the seats will fall out. Does that mean I will be limited to the .040 machining it has currently/ I won’t be able to have anything additional milled off to get the chamber size where I’d like it without damaging the valve seats?
Thanks,
Harlon
You should be good to mill the head or machine what ever.
