    i've got my head off being tested for cracks (3b).

    if I wanted to replace the head with a new one, what sort of work is involved? the new one comes with guides and seats installed, etc, do I just swap in my old hardware (valves etc) or do I need to have a machine shop grind everything to ensure it matches up?

    It would be proper to have the machine shop reface the old valves before installing them in the new head.

    well, i'll tell it like it is - in this case its a dumbass owner... me. i replaced the HG 6 months ago because i was too stupid to notice the steam was coming from the rear heater hose, but i did a half-assed job and didn't resurface the head or do a good job of cleaning the block. my aftermarket HG started to leak...

    so now i'm doing it all again. just have the head pressure tested and machined - its fine - and using an OEM HG. I started this thread just in case the machine shop came back and told me everything was fubared. that said, i'm still interested to know, since new heads are $800 to my door from AUS.

    sor is ~1000, not including shipping, and without any precups (which IIRC they want $100 each for)... roodogs is the way to go.

    Is roodogs OEM on that? I think some of his stuff is and some isn't, very helpful when I checked shipping OZ to UK, still have to order but never heard anything bad about him.
