What is  the up side and down side
of the three angle grind for a Corvair? Will the  seats get hotter?
Ron,
Compared to what? In my opinion a three angle grind is mandatory compared  to 
a one angle job. With only a one angle, it is impossible to set the seat  
width. and location.  However, a five angle job is even better. These  additional 
angles allow for a smoother flow transition.
 
 
Should you just do intake and not exhaust. What's your  experience? 
 
Mandatory to do at least a three angle job on all  seats.
