Roller rocker question for L-98s
I'm wanting to switch to 7/16" studs on my ZZ-4 which has the L-98 head. Can anyone tell me which roller rocker will work with the center bolt heads. I'm planing on using the valve cover adapters to switch to the perimeter bolt valve covers, but I'm thinking there will still be a clearance issue.
Thanks,
Dave

Re: Roller rocker question for L-98s (84c4)
you didn't say whether your using 1.5 or 1.6 ratio rockers. I don't think it will matter. The center bolt to rim adapter will raise the valve cover height. What is critical is that if you use roller rockers, get the full roller type. I ran an L-98 race motor with the Comp Cams 1.6 roller tip rockers. When I pulled it apart the stock style rocker seats and the rocker were blue from excess heat and I never revved the engine past 5500 rpm on the track. I replaced the studs as a precauition and I went to Crane full roller rockers when I put it back together. FWIW
