Two issues I see with this argument. First, the AFR's have the same port size and flow more, thus more velocity. Second, as you open up the stock heads you thin them out, that's OK but some have had issues with the rocker area breaking due to the higher spring loads coupled with the thinner sections. AFR's are a premium head. It all depends on your budget.

You might want to look at the Dart Pro1's. 225 intake runners out the box, fully assembled and handle 600 lift for $1600 from summit.

Default Cartek makes great power with LS6 heads

Cartek makes great power with LS6 heads. Look at the track times the cars run. AlexV runs 10.4's with 243 castings.

Mike can do some great stuff to these heads.

Depends on whose ports are in the LS6 heads. Some ports are better, some are comparable and some are worse.

Well thanks for straightening that out...I called you yesterday( about a S/C kit of a H/C setup) and found you very helpful but just wanted to make sure what i heard was correct.

You will be hearing from me soon
Thanks

I have a set of AFR's I want to get rid of. Practically brand new but I do not want to flycut so I need something else. Maybe some Ported LS6 and a fast 90/90? Who knows, I will definantly give you a call when I get these things sold.

Mike definitly knows what he is doing. Cartek heads are track proven performers.
