I'm building up a 400 street / slight strip motor (whatever that means) and am trying to keep myself from blowing money right and left. I wanted a little port work done on a set of 6x 4 cast iron heads but didn't want to pay shipping 2-ways because I am cheap. My engine builder recommended a guy here in the Dallas area and I am pretty impressed with him. We haven't bolted the heads on yet, but I got them back yesterday. He told me it would take 4 weeks, actually took 3. The flow numbers are not spectacular, but I got more than I paid for, which was $400.
