I just measured an intake valve. The distance between the top of the guide (no seal) and the underside of the spring collar is 9/16" when the valve is closed. Since the valve lift is 3/8", there will be 3/16" space left for the seal. This is 4.7mm, which means the teflon seals should fit with zilch room to spare! -- Kirbert | If anything is to be accomplished, | some rules must be broken. | - Palm's Postulate References:
