Hey Everybody, New tio the site and like what i've seen so far. Just put a Noss head with 20cc domes on my banshee, and it is popping from mid to top. runs great down low. Before the head it had right around 120psi on both cylinders, after it is right at 160psi. I'm at sea level at that pressure, and was wondering if there is any way I can run Pump Gas still (93 octane) with that compression or is that what my problem is? I have an adjustable timing plate that ranges from 10* retarded to 10* advanced. I was wondering if I could add some timing and maybe get it to stop popping, or am I going to have to run a mix of race fuel and pump gas. Thnaks in advance for the help
