I had an EGR fiasco recently and decided it was time to pull the head and it was well worth it. I took it to a local shop and they replaced 5 valves(4 exhaust + 1 intake), new seals and drilled out my egr port for $210. The head looked brand new and it was nice to have it serviced while I had a chance to scrape a 1/16 of carbon from my cylinder tops. All in all with a felpro top end gasket kit (Head, exhuast, intake and the like) + the 2 air tube gaskets from the dealer (If somebody else makes them then who?) I have about $310.00 into it with very little stress. Of course the FSM is a must.May be time for replacing valve seals on my 86 22r engine. I have read pro's and cons of doing this with the head on and off the engine. Can someone tell me the costs involved in doing this diy (either on or off engine, including parts and labor) vs cost of paying someone/shop? I need real life experience replies, thks.
