Charles Is still doing the flow test numbers on the 302 heads to show what they can flow.
Here is his latest video upload from yesterday. He talks about the next flow testing (at the 8:00 minute mark on this video).
A the beginning of this video (at the 1:00 minute mark) Charles talks about how the flow was topping out at 226 cfm, but then how he went back in for more bowl work with the results of 244 cfm @ 500 lift.
He is going to do flow tests with the 2 intake manifolds bolted up to the 302s next to finish up the results of his work on the 302s.

They are planning on using open chamber 675 heads for the final build, as they feel they they are more in line with the type of head that came with the '72 318 they are building.
