Im not sure if im adding to unnecessary chatter or not but im doing my header install today.
So far I got the plugs out, and front header out and im working on the crossover, I have the crossover heat shield off and im working the second set of 13mm nuts to free up the cross over. Up to this point everything has been a breeze.... the firewall side 13mm crossover bolt will not budge, ive sprayed and sat for several hours. Any tips? I think my issue is I have to use a swivel adapter and cant get enough torque. The crossover spins freely but at any point no go.
