I am new to this forum but I need help with a problem. I have a small block 360 cuda' and im running 340x heads on it. I built the car years ago and its a high 12's car. I started to get a coolant leak and it ends up that its coming from the header bold at the back of the drivers side head. I don't ever remember this being linked and i have never used a sealent on this before so i figured the head was carcked. But someone told me no thats normal. Before i go and pull the heads off Im looking for some advice. Any help is appreciated

Thanks

 

Ok well incase anyone reads this I talked to an engine builder today and he said that the heads had studs origionaly but when you change to headers and bolts you have to use sealent because they do infact link to water jackets.

Take care guys

 

He's correct, When you replace them you will need to use pipe sealant.
