Got my heads ported

This guy needs a lesson on how to test, run, and calibrate a flowbench. Not sure what some of you guys are seeing saying good job but this head with a 2.19 valve isn’t going to flow 410cfm while another port is 50cfm less. A well ported B1 head with a 2.300 valve takes a lot of work to get into that flow area 7289B5A8-187A-4586-B94B-D4497BC51519.jpeg
