World Windsor Sr. heads
 

In a couple weeks I will be starting the installation of all my goodies I have bought in the last year. Should I shave my Windsor Sr. heads??? I have a F303 with 1.6 rockers.

Thanks

I have the same heads and it seems that to get the most power out of your setup you need to shave your heads to up compression. I am not sure how much power you will get but I imagine around 20-30 horsepower. You might try giving World Products a call but when I did the guy was not helpfull to say the least.
Good luck.
