Crane Cams makes 'narrow body' roller rockers that fit under stock TPI valve covers. I ran them for years. There may be other manufacturers producing them also, not sure.

i run 1.6 rollers under a factory gm performance parts valve covers on my lb9 5 speed car... no clearence issues...... i went with jegs brand 1.6 ratio full roller rockers not sure if they are considered narrow bodied but, jegs guys told me they would fit and they surely did 
only 220$ bux and nice increase in performance for the money cant beat it.

You comp pro mags will fit. Just remove the inside baffels and bend the cross bars under the cover vertical rather then the slight horizonal pattern they are at now.
