What size header bolts??

[UnderPressureGT]

Can someone tell me the thread and size of the header bolts?? I have to buy new bolts and a tap

Also i have MAC equal lengths.. On cylinder 3, i cannot get the right bolt in because its too long and the header tube gets in the way.. what can i do? thanks

I used bolt with allen heads, the head of the bolt is smaller ,you casn also use ARP 8mm headers bolts,very easy to install.

i think it was a 1/4, but , definitly use allen wrench bolts..... the major reason why is you cant get a ratchet on the header bolts without the header getting in the way, with an allen head bold, get an allen head ratchet extention to fit, and your good to go, saves probably an hours worth of time...
