Replacing head gasket tips?

I kept fouling my number 6 sparkplug and noticed I had a header leak on that side. I tightened it up but still got black exhuast dust on the heads above the 4 and 6 primaries. I am hoping that replacing the gasket while stop my exhaust leak and keep the sparkplug from fouling out. I unbolted the passenger side header and scraped off the old gasket and went to install it again with the new gasket but it is a PITA. Does anyone have any tips on reinstalling The passenger side header?

For longtubes I typically pull the motor mount bolt out on the passanger side, and jack up the passanger side of the motor a few inches. Slides right in.

I dont think you'd have pulled the header though just to replace the gasket.

No the header is still installed and I can push it up to the heads but can't seem to line it up good enough to get a bolt started.

Get a buddy to come over and support it from the bottom.

Usually that's harder than doing it myself. I'd could have my gf help me if it wasn't for that getting dirty thing.

I guess that why I keep mine around, shes down to get dirty. I actually did it mysel, though. I stuck a piece of allen wrench (cut aff the L w/bolt cutters) in the head and hung the front of header, then support the rear and start threading. Worked for me. Hope it helps

Thanks. I think I'm going to stop by the hardware store and get a long bolt and cut the head off of it. I'm hoping that if I screw it in and slide the heads onto the stud I can line it up good enough to get some of the other bolts started.

I did that the first time. You can just buy threaded studs. Be sure to put them where you can get the vise grips in there good. Mine didnt come out to easy.

Re: Replacing head gasket tips?

What size studs did you use and which holes did you put them in?

Yeah I was going to take a header bolt with me to get the thread. I should of asked how long of a stud should I get. I thought about getting one about an inch long.
