C5 Head intel
Guys,
Its been a few yrs now since I looked into heads/cam packages. I started out with an aggressive cam and went to an 02 Z06 cam in my 6spd coupe for daily drivability preference. I have no plans to change cams again but thinking of doing something with the heads. Whats the best bang for the buck...AFRs? Or go with LS2's port and polished for quality?
If someone else has been thru this with dyno #'s for heads only that would be great!
Thanks

C5 Head Choices
LS2 and LS6 heads are 243 castings, the only difference are the sodium filled valves.
You could pick up a nice set of heads for about 1K. Cartek, TSP, SDPC, A&A all sell bolt on heads.
I would go with a slightly larger car, what the heck your half way there with the heads off.

With a Z06 cam I would think about any vendors stage 1 or 2 heads would do. You won't see any large gains with a cam that tiny, but they will really help with a decent cam. Bang for the buck I think the Dart 205's are really looking good. Small port, high velocity at a decent price. If you decide to really spend some money the AFR 205's or TFS 215's are both great heads.

Heres a thread of what somebody gained going to an aftermarket set of ported heads. Incredible results if you ask me. Cartek really knows how to port heads.

you won't see huge gains with a Z06 cam. The 2X is bigger than the Z06 cam but in no way big compared to what others use. I have been running the 2X cam for 6 months now and love it. Behaves well on the street if you want to drive it daily. I just wish I could afford a set of those TFS heads.

The 2x is an excellent street cam and as you said not too big compared to what people drive around on today. Hopefully the original poster will decide to buy something similar and really take advantage of ported heads.

I actually had the 2X cam in at 383RWHP and didnt like the shaking at idle (call me crazy). So I opt'd for the Z06 cam for a lil performance boost with stock like idle.
Sounds like unless I go with a larger cam changing the heads may be a waste?!? Has anyone changed heads only with any dyno #'s?
Thanks for the input bros

Vinci Performance installed a set of AFR 205's, out of the box no less, with the stock cam an picked up over 35 hp on a stock C5 without headers. If you milled to boost the compression a tad, I would think these would be excellent performers. These would also boost your low/mid range power as well as the high end. Shoot Tony Mamo a PM and get some information, he can help with any questions you have.
