I am looking for information on porting old style polyspherical 318 heads.  I understand there were a couple articles in Mopar Muscle Magazine in Sept '01 and Oct '01 detailing a build up of this motor including port work and head flow data.  Does anyone have a copy of those issues?  Does anyone have experience porting these heads?  I'm looking for information on where to grind, how much to grind, and where not to grind.  Thanks.           64Belvedere  

Talk to Ray Bell and Ben Simpson at the 318 Poly Yahoo Group - the latter has been "testing" the heads for a while now...
