Well, with a mild cam like the '02 LS6 cam, and the LS6 heads, dual exhaust you get 405 fwhp...
Stock LS1 cam, 241 heads, single exhaust 350 fwhp...
There you go...

ls1 heads 370rwhp
ported ls1 heads 390rwhp

LS6 heads with no cam change on an LS1 will give you around 20 rwhp.
1- They are 0.5 bump in CR
2- They flow around 15cfm more
Add a 231/600 lift cam for another 30rwhp
so I would say ~ 40-50rwhp

Thanks, Predator. That is about what I figured/guessed also. I saw one post that said 20 to 30 at rear wheels would be pushing it. I would be mighty disappointed/mad if after all that work and money I only got 20 or 30 more. What he needs to keep in mind here is that the power is the sum of all cylinders together. What I mean is, 20 to 30 at the rear is easily doable with a cam only. Like you pointed out, people forget that the LS6 heads not only flow better, but bump compression also. Breaking down the power increase by cylinder, a 20 horse gain/8 (total cylinders)= what, a 2.5 horse gain per cylinder? A very low estimate IMO, not a pushing it figure. With the cam and heads he is talking, a 5-6 horse gain per cylinder would be very much an "in the ballpark" figure.
