My heads have cracks radiating thru the web between the valve seats, some thru the seat themsevles.

Should i install liners and replace the seats, install liners and just do a valve job or buy new heads?

Anyone with experiance your input would be appreciated.

thx

I would go with new valve seats and liners, guides, etc.

You can probably buy reman heads that already have that if your in a crunch for time, and probably comparable on price too.
