this could be the reason why my gx coupe didnt run all that good, the head was milled and i took another 1mm off the head, had a 1400 bottom end, 1200 flywheel, twin su carbs and a 290 degree camshaft. i don't want the same problem on the ute, i want to build something that will run good on street without problems. so i guess rather just use the same cam, maybe cut a 1200 flywheel and just do bigger valves on the gx head?
