agreed...depends on who did the work and how good the p/p is.
budget ported 243s could only gain you 20-25hp
professional ported 243s could gain you nearly 50hp
poorly ported (fucked up) 243s could cost you power

agreed with teke. You can gain 15hp bolting on a stock 243 head, 40+hp with a proven LS6 head, or who knows with a jacked port.
Checkout www.texas-speed.com we offer ls6 heads fully ported & brand new for abut 1k for the pair. Cnc work & assembly can also be done to your cores if you'd like!!
Becareful choosing a proven porter!! Spend some extra time in the dyno section looking for independent results!

You might even spend some time off this forum looking for independent results.

I guess this is not an indipendant result but;
with CARTEK 4X [hand ported LS6 heads] and a CARTEK 4X cam, my car made 507.9RWHP, through a 12-bolt with 4.56 gears...
Fast 90/90, 1-3/4" headers and bolt ons.
