914World.com _ 914World Garage _ Which one do I have

Posted by: BarberDave Jul 14 2007, 02:22 PM

I have a set of 2.0 heads I am going to send out to be rebuilt . I also have a set of 1.7 heads ,i remember hearing that the 1.7 rockes are better?? Right or wrong ! If there are diferences in the 1.7 rockers, how do i identify which ones I have . I plan to run swivel foot ends.

The only difference is that the hole where the adjusters go is smaller. I believe it's 8mm on the 1.7 ones, and 10mm on the 2.0 ones. Which means that the good swivel-foot adjusters (the real 911 ones!) will only fit in the 1.7 rockers.

YOU are correct, sir. (Ed McMann to Jonny Carson) You will have to trim some off the rocker to install the Porsche swivel feet adjusters. Check Jake's site I think he tells you how much to trim off.
