In over my head (rocker geometry)
i am in the final assembly stages of my engine. it is a 383 with eddy heads. comp cams magnum roller rockers. cam is comp cams. 525 lift. i have already verified top dead center on the #1 cylinder and check for valve to piston clearance (.085). i am checking my rocker arm geometry and this is where my problem is. i cant get my head around it. I assembled one intake and one exhaust rocker and marked the tip of the valve stem with a marker. then i rotated the engine a few times by hand. the marks are dead center of the valve tip. the adjusters on the rocker arms show 3 threads showing. does this look right? or do i need longer push rods? if i do a longer push rod will if change my geometry? here are some pictures.
