I try to use the pins and corks whenever I can, cuz the clean-up is so easy. But if the heads or decks were machined, this pops the intake up out of the valley. This causes misalignments all around the intake that all have to be corrected.Occasionally the pins and corks just gotta go.
Just make sure whatever intake you are using has enough meat on the bottom of the port to securely clamp the gasket against the head.
