I had my Cast Iron Head redone by Indy Cylinder Heads in Indiana... they did
great work and saved a badly damaged cast iron part.
it's Very Expensive.... $500 for one Pocket. But these heads were done By
Hogan many years ago and had been angle milled about 2 hundred
thousandths.... and the Port work is exceptional for a 23 degree head. ( now
a 21 degree head with the milling )
Guess my point is that like an aluminum Head.... Most folks can weld it...
but it really needs to have some things done that the average machine shop
doesn't do... like Heat sinking prior to welding and so on.... Look Close
at the folks who say they can repair something.... most times it's worth the
money to do it right!!!!
