So with the engine installed there's not a lot of room between my valve covers and firewall. I didn't want to change the position of my NP205 and have to worry about front/rear driveshaft length, so the engine is fairly close to the firewall.
Not much room between passenger side valve cover and firewall.
The Doug Thorley TRI-Y headers (THY-324Y-C) hit the firewall and won't work.
This high pipe out of the Thorley headers hits on the passenger side.
