I do agree that an LS head is not worth porting unless it can help in the race class one is in.
The Type R Prep port n polish that David Green did on my B16 head with the valve job, head work that was done by Extreme Performance in Stuart, FL along with the head/intake/exhaust package I used made the power difference in my LSVTEC.
He also did some port work on a stock B16A engine for a guy who didn't have a lot of money to put into his car just to see what a difference would make. I went for a ride after and the car picked up a lot of low end torque and through the mid range. A stock B16A with low end torque? Yep.
Flow rates through the head can be measured so therefore a PNP job is worth it and even more so when the rest of the head is done properly.
For PNP work: David Green 321.632.6558. Referred by Angela. He also built an LS Turbo for a guy up in SC if you would like to ask him questions about the build you can call him.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
