I have talked to Bret, he doesn't recommend the Darts for a stock bore. He recommends the 243's that Joe Mendelis designed the port for. They are a bit pricey, but I am willing to spend when the product delivers. These heads have been on championship cars, so I am going with his heads/cam package, prob solid roller, and possibly setting up a vic jr intake as well. Just wanted to make a post and see if there were others I have not considered.

The TFS heads might be great, but I don't know who Vengeance had design the port they CNC so I am not considering them. I hear the newer CNC version ET is releasing on their TFS heads is supposed to be really good, but I haven't seen any results on those. I know the guy holding the 9.90 stock cube H/C record was using AFR's, and I don't see any TFS results better than mid 10's.

A comparable flowing 243 casting will be larger than the TFS 215. Don't get caught up in high lift airflow, it just isn't that important. We've made 2hp/ cu in with heads that stalled at .600" and had .700" cams. The airflow at .300"-.500" is where the power is, even if your running .700" If you go .800" lift then start looking at the .400"-.600", if you go .900" lift then start looking at the .500"-.700"
BTW, all of the TFS/TEA CNC ported castings, including Vengeance heads, are all the same CNC program, the difference is in the details.

Just to clarify for you guys.... The TFS port was designed by Brian Tooley of TEA/TrickFlow.... We had nothing to do with the design of the TrickFlow head other than some preliminary testing. The TFS heads have proven to be one of the best heads on the market time and time again by MANY different shops AND individual customers. Im not saying they are the only choice, but they should definately be in the top 3.......

We've been extremely impressed with all the Trick Flow offerings for these LSx cars thusfar! In fact, I'll be ordering a set today to go on a customer's car - hoping for 500rwhp.
Brian and Mike over at TEA are definitely two of the most knowledgeable guys in this industry.
