Yella Terra Question I'm considering installing Yella Terra roller rockers on my C5 with MMS 220 heads. I've looked at threads about the installation and have a question for those that have used them. It would seem that most have used shims to get the geometry correct and I can relate to that. Yella Terra information also discusses having to grind the pedestals in some cases and I'm not too certain about doing that. I've had the MMS 220 heads for about a year now and I'd like for this install to be relatively simple. What are the odds of having to mill the pedestals to get correct geometry on these heads?
Here's what I have:
MMS 220 heads with 8019 springs
Johnson ST2116LSR short travel lifters
Comp Cam 221/228 (LSL/LXL) @ .050 114 + 2 Gross Valve Lift .608/.606
Manton 11/32 pushrods
Also, what do you think about the Ultra-lite rockers for this engine?
