Whats up honda-tech I am in the process of rebuilding a GSR head I picked up and well heres the pictures:






Here are the valves that were in the seats that say screwed up valve



I really don't know what caused that to happen to the valves (I got the head in this condition) other than maybe the valves were to tight?

There are also two other valves that were white colored.

My question:
I obviously know I need to at least replace those two valves, resurface the head, and have it pressure tested. Should I replace all the exhaust valves? The intake valves look fine. Also the valve seats look alright but I could be wrong.

One more question should I do anything with the valve guides?

Thanks.

 

Take it to a machine shop and ask them what they think.

If they valves look fine, I don't see a reason to replace them. HOWEVER, a lot of times something will look fine, but it's not.

Head down to a machine shop and have them take a look.
