It's going to depend on the rest of the mods such as exhaust, intake, etc...

There's a Dyno Results section on this site. Lots of TFS results there.

I think he is talking about the tfs specific top end kit with the 230/238 cam or whatever it is.
The kit is good but could benefit from a better cam.
We have a combo using tfs220 as cast heads that is about $3800 that comes with a fast92 intake and 92mm tb as well as every gasket bolt and seal plus fast 42lb injectors that will make as much power or more and be quite a bit more complete.

Yeah that would be it. Looking to make my 64 nova a little quicker. Your kit seems like a pretty good deal. What’s the specs on the cam? Does that come with rocker arms or can I use mine? They have the trunion conversion.

From what we have seen, you can reuse your rocker arms.
The cam is our High Lift ASA Cam. It has a very aggressive muscle car idle for the guys looking for a nostalgia ride but doesnt need a huge stall if auto to work either. 226/236 .600/.600 110 lsa.
We have a few videos on our fb page of the cam.

I’ve got a 4L60E w/3200 stall. I asked about the rockers due to the description of the kit saying it needs to use roller rockers. I’ll check out your fb page.

Tfs recommends rockers based off their own reasons but i have seen 0 issue so far with stockers.

Good to know. Upon first reading I thought had to use their expensive rockers.

looking at flow #’s of the 215 & 220 heads at TFS website. As they sit the 215’s flow more. So I’m guessing the 220’s can be cnc’d to flow more than them?

The 220s will flow nearly identical iirc on a 4"bore vs 215s or very close. The 220s can be hand finished to flow more or cncd to a 225-233 runner and flow quite a bit more. Dont get too caught up in the numbers though. The tfs220 is a stellar head out of the box as is.
