With jenvey itbs, a bit of headwork etc, the engine made good power and could breathe well past rev limit.
Now with more compression, upgraded valvetrain and head work the engine is crying out for a little more lift and duration to help it breathe.
I am now looking at the 272* maruha cams to gain a little more power for a lot of money spent...hindsight value $$?
Picking a cam that gives upper rev limit power without sacrificing torque lower down in the rev range is a bit of a balancing act when trying to maintain street manners.
If you go too large a duration you will move the power higher up and need to rev it hard all over the neighbourhood . Not the most desirable thing with the jenveys barking for attention already. You get stuck with a car that doesn't make the power in the rev range you're most likely to use.
It sounds like what you first suggested would see you achieve reasonable power gains for reasonable costs without losing street-ability or having to start forking out for upgrades like springs, lifters, shims and labour costs etc.
If likely to become a naturally aspirated power chasing addict regardless of compromise, look toward the larger solid lifter cams at least.
