Default TSP headers
Hey guys, so I'm looking at buying these headers for my 07 NNBS with 4.8 and im curious of yalls thoughts on waiting to put these on before I cam it. Im worried about the notorious header bolts breaking on me, especially the back ones. Anyone have tips to get them without breaking except for just the PB blaster.

I have TSP 1 7/8" on my GMT800 Tahoe, and I have to say I like them for the price and the fit. I'm sure they make the exact same power as the next guys, but they fit without drama and are pretty well made for
being Chinese. Imo.

If any bolts give you trouble use a small propane torch to heat them up and they should come right without any drama

I just did some on my wife's 04 sierra and I sprayed all the bolts down 3 days before with lucas tool buddy. Then one a day after. Had one with the head already missing but had enough sticking out to put a nut on it with a drop of red loctiite and it came right out. The oil actually penetrated about half way down the threads and they all came out easily. I consider myself lucky.

What gaskets are you running now a days? As soon as i put my felpro gaskets on last summer i had horrible leaks. Looking to get something else in there to fix that. I have heard Earls header gaskets are legit

I would just use factory gaskets. They seem to work the best. At least what i have seen and read.
