These heads are way more than what OP needs, his cam is only a 268...2.02 intakes and porting will actually give him LESS torque where he needs it on street RPM's. You certainly would not want to open up chambers, he needs as much comp as possible. I purposely didnt recommend Edelbrocks as he wont have enough comp to heat aluminum heads and get a good burn.
With that small of a cam, OP will get more street power with OOTB EQ than reworked stock LA, Edelbrock or worked big valve Indy/EQ's. Simply a waste of $600+.
