Exclamation Pro 1 Dart heads

I'm thinking of purchasing some heads from another member. They are the Dart Pro 1 heads 225's. Has anyone had experience, or know if they are worth purchasing? I will be getting a LS6 or FAST intake, and doing a cam swap. Headers and duals with dumps. If you know, post some results.

I touched mine up a bit, the bowl area was not the best on mine, i had to dig the chambers out to match the bores and get the 11.5 comp ratio i wanted, i also smoothed the as cast finish in the runners.

I also have a set of 205's that I am going to be putting up for sale this weekend. I am just finishing measuring the spring installed heights and spring installation on the 2nd head.

The 225s are a good choice. I personally had the 205s. I wish I had 225s because of the potential to grow with them later. My only suggestion would be some minor port work and some milling to increase the CR.

I have the Dart 205's that are ported. I like them.

Agree^^^^^^I have Dart 225's, flat milled .022" for 58 cc chambers (11.31 SCR) and ported by myself. No problem with the performance.
