Harland Sharp Roller Rockers -340 ??
I had PRW aluminum full rollers on my 340 and last week nbr 7 intake valve adjuster broke off
Lucky I found all the pieces in the head.. but I'm not taking any more chances with these.. they've been in the engine and fine since last year but after a smoke show I heard the valve clacking..
Fast forward, I bought a Harland Sharp set up from Summit .. love the rockers but the hold down holes through the shafts are 3/8 and the ones on my heads are 5/16!
Is there any way to use these new Harland Sharps without tapping out the heads for 3/8 studs/bolts?
