I keep melting a spark plug

[nvmytsl]

for some damn reason i keep melting a spark plug on the third cylinder..is it that my injector is out and im running lean? anyone know what can cause this??

Swap injectors and find out if the problem moves. How does it idle?

it idles fine besides the cams..it also runs fine but sometimes when i step on it hard it would sputter at the very top. Im gonna move the injector to a different cylinder and see if that does it as well..if it does i guess its time for a new injector.

Sounds like you burned a valve in your head. Check out the injectors, but I'm betting its a burned valve. It happened to a friend, and he would change his plugs, go for a drive on the highway, and the one would melt.

the thing is tho is that i just had my head removed, cleaned and checked over, i even think they replaced some valves. I gotta call up my shop and ask to make sure but it was just redone.

would anyone here know the resistance that blitz 660 injectors should have?

I don't know the answer but it shouldn't matter so long as the resistance is the same on all of the injectors.
