I have a 347 stroker with holley heads.These heads were fine on my motor before I stroked it ,but I think that I might get more power from something bigger.These heads have 1.90 intake valves.Should I have them reworked with bigger valves,or should I just get new ones like the afr 185's? Is it even possible to put bigger valves in the holley's?
