4spd, 3.91
Heads, 516 Closed chambered 79cc
Been running them all summer, car been doing great since i found the right tune for carb and ignition.
160 - 165psi across all 8 with .39" headgasket.
Car has alot off bottom torque wich was the purpose with the build ( My first ever )
Got bored and wanna learn new things so i figure, I wanna swap the headgasket to a .18" for some more cylinder pressure! ( Have valve clearence ) Lets port the heads? Been reading books /articals/ytube about it.
The plan of course is some more power. It's just a cruiser but hey i wanna get as much out of it as i can with the parts thats in it.
So i jumped on it, 19h later the first head is done i think?
Intake.
