Default LS6 heads on a stock LS1

Just curious to what gains would be had by bolting on a set of LS6 heads on a stock LS1(stock cam and intake).

Or, even take it a step further and do LS6 head/intake and a stock cam.

I'm not planning on doing this or anything but I was just curious after browsing Ebay and seeing Ls6 head go "fairly" cheap.

On a stock LS1, prolly about 15-20 rwhp. Not worth doing the ls6 conversion IMO. If you found a set of ls6 heads for cheap, go for it, I would and then get them ported later.
