Default 4.8 Truck motor Gen IV - 862 heads exhaust manifold bolts stripped
Guys,

I have a 4.8 truck heads that have 2 or 3 exhaust manifold bolts that are stripped.
does anyone know a helicoil part number that I can use to fix this ?

I assume I am not the only one with this issue.

Thanks,

Any machine shop that does LS heads will know. This is a VERY common issue.

They are 8x1.25 thread

Don't know the part number, just get a helicoil kit for 8x1.25
