Chevy2inreno and Joe,
Both came thru fine, Thankyou.
Joe, sorry to hear the motor was not in better shape, just glad you caught it now, later would be much worse.

Duececoupe,
Here is a flow from one of my heads:
.100 61.7cfm
.200 115.6 cfm
.300 171.5 cfm
.400 207.9 cfm
.500 229.1 cfm
.600 242.7 cfm

Headers are 1 5/8 tubing with 37" primary's, 8" long collectors that are 2.5" diameter. Let me know what you find.

I am really busy now getting things/parts all arranged.
