Well came to the conclusion that I have a bad manifold and its not leaking by the broken manifold bolt, so I will be buying a set of long tubes and the best exhaust manifold gaskets, I did a search and percys header gaskets look to be the best is that true or you guys know anything better

 

the best gasket is the stock gasket. i have re-used mine 10-12 times and they still seal perfectly.

 

My stock ones are not sealing up at all end up changing them with a set of felpros still leaked i looked again at the felpros and can tell it leaking on cylinders 3 5 and 7 on bottom side of each cylinder, cylinder 1 is not leaking and that has the broken manifold bolt

 

try a new set of OEM gaskets. that's what everyone on the forum uses.

 

im running the percy's....

 

New GM MLS ftw, imho. ~$25 , you can't beat them.

 

You got a part number and or website to pick them up

 

I don't off-hand. I ordered my last set from the local dealership. Sdparts.com may have them.

 

Alright I will do that thanks

 

Stock mls gaskets are hard to beat.
