you take the motor to your local machine shop
clean block $160
bore and hone $150
deck the block $50
recon the crank $150
Master rebuild kit $670
recon cylinder head $180
take the parts home and assemble
total cost $1360
I would have the head modified for adjustable rockers, which is bout another $125
optional:
If I were to keep a 470, I would personally spring for a Edelbrock aluminum cylinder head (ford FE engines) and drill the big hole in the end to avoid having an iron head on an aluminum block. this would solve a major portion of the problems with head gasket failure
I would also laser cut a bore spider and tack weld it in place prior to machine work to stabilize the floating bores. this would solve most of the remainder of the problems with head gasket failure
then there is still the cam snout seal issue
