thanks for the speedy reply. i'm not sure what EXACTLY the shop is wanting to do to the head that makes thier price so high (i will find out on monday when they reopen). but, my question is, if all they want to do is put in new parts (no mention of resurfacing) and grind the valves, i would like to do the installation myself (which it sounded like you were in favor of) therefore saving a lot of cash. the only mention of things wrong with the head other than the valve parts was what the machine shop called some nuts that the injectors screw down into. they said that a few of them were stripped? i thought that the injectors threaded right down into the head. i'm confused with this nut thing. if you can shead some light, thanks.
