Ok, the decision has been made to stay NA.....my 05 mn6 vette is at full bolton status now.....my question is, what are the benefits to going with aftermarket heads (tfs225) and a custom cam vs. Custom Cam only? I mean on a street driven car, would the heads make that much of a difference to justify the cost?

Benefits ?..... More HP and TQ from a smaller cam, which on the street means a more DD friendly cam, or just flat-out more HP and TQ from the same size cam used in a "cam only" setup.

At what point/size cam do you begin to out flow the stock 243's?

Almost any LS head that has been worked over will out flow a stock 243

Let's take the easy road. The only downside, as long as you pick a quality head, is cost.

What could I expect to see for hp/tq on an ls2 with custom cam/tfs225 heads/portmatched fast 102 and long tubes while keeping good drivabillity?

Heads are the key piece of any build, so yes they would make that much of a difference. Unlike a cam that only picks up power at a certain RPM range, proper heads usually pick up power everywhere.

As someone else mentioned, the benefit is that you can run a much smaller cam (for driveability and efficiency) and at the same time make the same kind of power as just a big cam only.

With my heads and baby cam I am making the same kinda power as people with a big cam only. Except that I have significantly more power down low and it's easier to drive and get better mileage.

Great thanks...I was just needing a little push to make the move. Brian Tooley will be specing/designing everything and eps will be doing the tune.

One of the mods...JayplaySS2 has a C6 with stock short block, TFS 220 heads, and a decent sized cam which dynos over 500 rwhp. I can't find his thread right now but to answer your question...YES heads will help alot !!!

In short, yes heads are well worth the cost when paired with a nice cam and full bolt ons. I took a similar path -- cam + full bolt ons and then added the heads & fast 92 at the same time. I went with budget heads to save cash for a N2O setup and even the budget PRC heads amounted to huge gains across the powerband.

If you're still running street radials, your next mod decision will likely be tire related.

I have been following "jays" build,very impressive! I am running a pretty sticky tire now at 400rwhp and can be tough to stick w/o some hot street/tires. plan to run R888's next go around as handling is of great importance to me being on coilovers now.

been getting prices on installs from reputable shops.....but wondering what a fair price would be for heads cam install (labor only)?

You're probably looking at $1500 easily for just the labor to do heads and cam, probably more depending on where the shop is located.

If I went with a 403ci stroker kit in the future.....Would a set of ported tf220/tf225 heads be to small?

We use the TEA TFS "As Cast" 220cc heads on 4" stroker motors all the time! They work great!

500/500 many times with those heads and a good camshaft to match.

They're very well priced and have the capability to be "opened up" by your porter of choice at a later date if you wished.

great,thanks!
