You could add one of these if you think your fuel is getting that hot.

I think running a dead head of fuel pressure is not a good way for a fuel system to work IMO.

I ran a dead head fuel set-up on my Camaro for a bit, because I was too lazy to install a return line.

Forgot, did you advance the cam timing or retard, or the same cam timing since the last build?
