generally speaking, you want more exhaust duration than intake duration on most factory and after-market street heads to help balance the flow rates. best option is to order your cam from one of the many regular contributors here, thay can consult with you and order a cam that will best suite your application

Neither ... what heads you are using is the minimum information. You really NEED to give a whole lot more details in order to get an educated recomendation.

The engine conbination in that thread was UNDECIDED and the camshaft should be one of the last items you get because it depends almost totally upon the COMBINATION.
