Pushrod Clearance at Brian Margaret blog

Pushrod Clearance. Doing a dummy assembly and checking, i find that the exhaust pushrods are touching their respective bores at around full lift. Dry tappet clearance is the gap between the rocker arm and the valve stem cap when the lifter (tappet) is dry and fully collapsed. When checking for pushrod clearance (at the guideplates, through the head), don’t get carried away by overclearancing the passage(s). There are actually four different trend taper styles for the larger diameter pushrods. Manton recommends.010 clearance between the pushrod and head. I'd be very concerned about the pushrod rubbing on the head. Taper will most likely affect the overall pushrod performance, where a clearance only reaches back from the ball to the largest diameter of that pushrod. In our case, two turns out generated the proper clearance, meaning the pushrod length needed for our engine is about 6.800 inches. Hi, can someone please tell me the recommended minimum clearance for the pushrod to cylinder head clearance. 23* sbc 600 max lift. Too much clearance allows more pushrod deflection.
