Listers,
Thanks for all of your responses. For you additional information the rockers
are the Goodparts 1.55/1 ratio. My question really related to the average of
30 PSI loss in compression and yes, with a nearly10/1 compression ratio I used
to have from 193 to 204 PSI. I didn't expect any noticeable difference in power
just from the roller aspect of the rockers but did think that the change in
rocker ratio might improve power slightly. I believe your responses have
answered my question. Overlap at idle reduces the compression somewhat because
of the increased rocker ratio.
