you can use a G head on a original Swirl port engine and ecu no problem.

^ 85' G head with 90 TBI roller cam on a 2.2L with the 84 t1 pistons

The swirl pistons are like 14cc and the G head pistons have a 9cc dish (I think, I know it's they're smaller) the reason is the swirl had 6cc less head volume, so if you used the right pistons you wouldn't need any machine work.

The best flowing head is the 83-85 "445" & "287" casting head. It flows 10% more air than the 86-94 "782" head which makes about 10% more torque. The "G" head would be a good choice for a light car, while the "782" or "fast burn" head will be better for a heavier vehicle due to its better throttle response and higher port velocity."

Nobody is questioning wether the G head will start and run with a swirl cal and later pistons. But it should be noted that the lower compression and slower burn of the G head will result in somewhat sluggish performance unless changes to the compression and cal are changed.

it ran fine on the 2.2 cal that was in the car,88 shelby z
