Windsor Sr. vs Trick Flow TWs
 

Which one (Box Stock) will make more power on a stock bottem end (302) naturally aspirated? How about with a power adder? Also, how important is port volume. Will a larger port volume always make more power, or does velocity play a more important role?

1989 lx notch

bolt-ons,stock heads/cam
60'- 2.07, 8.90@78, 13.93@99

TFS all the way...they are the best heads on the market as far as power next to the Canfields and AFR 185's....emission legal that is.

12.564@118.49 on street tires is my best so far. Still untuned

The TFS Twisted Wedge heads just plain whip the SR's out of the box.

Anywhere, any time the TFS heads beat the World Products Windsor SR's. About 15-20cfm usually.
