Guys- I got a weird one here I wanted to run past you all. SBC with aftermarket heads. The valve stem tips are very low relative to the top of the retainer. I have no idea why- it was just born that way, I guess. I don't want to take the heads off, nor spring for a new set of valves. To get reasonable rocker geometry the rocker needs to be "leaned back" more than it is now (shorter sticks would fix the problem). However, when I do that the underside of the rocker arms touch the tops of the retainers (1.45" springs). If I put some lash caps on top of the valves that will almost certainly give me the retainer clearance I need to install shorter sticks and lean the rockers back a little more. SO...... is this an OK way to proceed? Any problem running them with a solid lifter cam which, of course, will have some amount of lash clearance in the valve-closed position?
