Well i stupidly resetted the engine light and wont' come on for me to check, but saw some sign of leakage from the head. I was told it's probably the head gasket, and that i need to take everything apart...

If i supplied the parts, how much would a fair person charge for labor only at a shop?

I'm thinking while i'm at it, i put some upgrades, or type R stuff in it... any suggestions? or would the cheapest way be to just swap it with a good gsr head?

Thank you!
