Bean looking for a while about the 1.6 gti engine and have seen that the afh head on the avy engine is the way to go can that be done ? Looking for it to be run on bike carbs dose anyone do manifolds for them? And what's the best way for ignition dizzy or something like mega jolt ? Or if anyone else has any ideas on a n/a engine that's easy to tune with as much bhp and torque as possible let me know thanks Paul
