Why not start with a better head for porting?
By Royce Peterson - 04/15/2002 3:52:31 AM; IP 152.163.201.76
The C8AE-H or D2TE-A casting is much more suited to extensive porting due to the intake floor being higher and the exhaust flange being suitable for either bolt pattern. You can use a Medium Riser intake gasket as a template, a very straight intake port is possible.


Those early heads have ports that measure larger but need to be welded at the bottom of the port to flow well. That can cause leaks and warpage, plus the weld is very hard to grind.
