Looks nice, I’d still like to know how the Dart Heads compare to the Brodix. Clowns to the left of me, Jokers to the right. Here I am....... | |||

Not really an apples to apples questions because there is not one Pro 20 or Sr20 head out there! Too many ports from the same castings. But from what I have seen they are both great heads. For larger motors I'd lean towards the Dart heads, they have a larger port. I have a Pro20 632 in a 1840 pound dragster that has run mid 6.70's over 197 in good air, normally mid 80's at 195 plus. A friend has a set of SR20's that's a little lighter but runs the same. | |||

When you come home and are blown away! Some companies just get it and take the opportunity to make a statement in branding. The boys down in Texas have figured it out. Chris Frank and Mike Shabareck we can’t wait to represent! #frankenstein. Check them out at FrankensteinED.net   | |||

Scott, did they flow the heads when they arrived and then flow them when they left? If so, what were the difference in the numbers? Will be interested to hear/see power gains on track as well | |||
