Cometic Head Gasket
I wouldn't listen to anything shady dell has to say. They built a motor for me in the past . The heads leaked so bad it was unbelievable. They told me that they always use moroso block seal.
Ryan is the shadiest guy I met. Here is a pic of what happened to the ne and only motor they did for me. He is and A$$ hole as far as I am concerned. This was all due to shady machine work and parts that were not mine. Needless to say they paid for what they did but it took over 1 1/2 years. But I never got all my parts back. I got tired of waiting.
If the motor would have stayed together I would have never known they switch my parts. I don't know where he gets the pics for his web site. when I went there and walked in his two car garage all he had was a Harbor frieght drill press with a mill plate attached set up on concrete blocks. What a joke that place was.
The CNC milling he had done at a garage in the boone docks that he took us to was a 1/8 inch off from side to side. They ruined three blocks on me trying to stand good for what they did. Two X blocks and a Resto.
He uses other shops to do his work. I wouldn't let him build a Outhouse. Your **** would bounce back and hit you in the ***.
