Heat exchanger removal results question
 

This is what I was left with after removing my heat exchangers. I am just doing a reseal but wanted to investigate my exhaust valves. Its an 85 with 70K.

Three studs were left in the case. Should I pull all of them and replace everything because it doesn't look like I will be able to geta tool in there to clean them off properly or should I just be happy I didn't break any and clean them with a wire brush ,put on some anti seize and replace the other hardware.

The oil tubes look ok but I think I would like to replace them. These don't look original? How do they come apart?

Heres a sample of what my exhaust valves look like. I have all the books but would like some confirmation I am on the right path.Thanks for your help Doughttp://forums.pelicanparts.com/uploa...1264393869.jpg

Great job getting everything apart without breaking somthing. You should just replace the ones you got out. Just clean the remaining ones up a bit and use anti-sieze like you said. Those are long studs so there is no reason to change anything.

Hard to tell anything from just looking at the valves, you will need to do a compression test to see if they are seating properly. It is a pretty easy process especially with the engine out.
