Bought a set of Yella Terra rockers today......... Well, Im comlementing my new SII heads with those new Yella Terra 1.7 shaft mounted rockers. I was told that with my big cam (228/236 .571.602 111LSA) That my stockers might actually flex due to the high lift. So I decided to buy the Yella's. If at least anything, they look sweet 
. My question here is, what is the proper way to install shaft mounted rockers? Now I'm a beginner at this internal stuff so please bare with me. Thanks

Re: Bought a set of Yella Terra rockers today......... Proper leverage and geometry will affect P to V clearance, less deflection increases actual valve lift also. This will tighten things slightly. I also believe actual Ptv is more on running engine than what is checked at rest because lifters bleed off lift and this shortens duration slightly.The thin weight oils and extra spring pressures we use adds to this loss of lift etc.
