Change rockers 1.5 to 1.6?

what's wicked funny about that? I thought we were being serious! lol OK so I guess if I want to up the #s on that thrrrre fourrrrty I should go with a bigger cam and maybe more compression. Already have dual valve sprrrrings, can't remember pressures off the top of my head. Haven't checked cyl. pressure but everything is new. dyno time only. Just expected a little more. Stripping engine bay for paint before engine goes in. Now is the time to make changes if any. What are your opinions on the cam Rustyratrod sugested?
