I finally got this customers heads and intake on the flowbench. I was really happy with the .300 lift number but these heads were used and already had a little work done to the short turn. They climbed pretty quick and he’s running a .640 lift cam so they recovered nicely. Left column head, middle column his two inch spacer, third column no spacer. I could have probably helped that some with a little duct seal radius on the carb flange.
