You're headers sound nice. Most 4V headers are 1 7/8" and still have a little taper to fit the huge port. If you look at the port, much of it is wasted space. The 2V port, despite being smaller, mov
I have the Edelbrock for the 4 barrel Cleveland heads. Their ports are considerably smaller than the intake ports. ( They claim this gives more low end tork). The original cast iron intake had runner
That grind's low on lift for the duration. The 4V heads really like more lift. The 2V''s have less ultimate flow but get the flow at lower lifts. My books show a 6.5" power valve. As light as the Ti
I'll have to check. The Aussie heads are a different casting with some minor differences but I never paid much that much attention. I'll check and see what I find. Dan Jones
The reason for the Crane lifters is to decrease the lift at low RPM and provide more torque ( or so they advertize). Maby so. I get 15 inches or better at idle. For a long time I had a vacuum gauge m
