the last bolt n the back on the passenger side was the only 1 that gave me trouble, had to get it under the car w mini turns

ryan_89_mustang

Yeah I never had any problem getting the bolts out but then I realized I didn't know what way the gaskets went. Anyone know for sure?

ryan_89_mustang

It is some parts store brand I don't recall.

the softer part will go on the side the header is atleast thats the most sensible way

ryan_89_mustang

Alright I guess I will try it that way then.

softer side is too the header, hope you have better luck than me

like i said the way i did it, tighten them all down starting from the middle make sure u evenly torque them. then just keep doing it till there pretty damn snug, with a small wrench dont use like a 30" breaker bar, then when they all are, start it up and keep going around and tightening them, then once they all wont go anymore and the car is fully warm, turn it off, come back a hour or so later when its all cooled, start it up, and keep tightening, once fully warm, shut it off, do that 2/3times, i used a small about the size of my hand wrench cuz i have aftermarket smaller head bolts "7/16th", do that and u should be all set.
