Re: Shaved Head response/question

["Ken and Susan Buck" <phillyscca@mail.enter.net>]

Someone asked about how much they can shave off their already shaved 
head.  The answer is basically, "you can take off as much as you 
want."  BUT you will wind up with an interference motor, meaning that 
the valves will extend in to the area of piston travel.  This is not 
a problem until the timing belt breaks, at which point your 8V will 
act like one of those 16V engines, bending your valves and 
possibly wrecking your head.

We have done some extreme head shaving on some project street cars 
with great success.  But we do have one problem which no one on this 
list seems to have an answer.  Let me explain....

When you shave the head, it will change the cam placement on the 
timing belt, actually retarding the head timing.  The expensive fix 
is to buy an adjustable cam sprocket.  SOMEONE makes an offset 
keyway, but I have no idea where I can buy them.  IF ANYONE KNOWS 
WHERE I CAN GET OFFSET CAM KEYWAYS, please let me know.  
These will allow you to advance the sprocket to compensate for the 
timing difference without having that huge adjustable cam sprocket. 

  
Who has an answer???????????????????????????????
