Polling your thoughts on a set of heads. Not to beat a dead horse but I'm in the market for a set of heads. These are all around the same price (from TSP)

#1 PCR 215 $2149.99
#2 AFR 205 $2285.99
#3 ETP 215 $2399.99
#4 TFS 215 $2399.99


The car these will be going on is an 01' A4 Z28 LS1 346 with your basic bolt on's like SLP lid, cat-back, LT's w/ory, gear, stall, OH! and a cam.
The cam is: .598int/.600exh and 226*int/230*ext with a 112lsa w/ ESP lobes.

I will more than likley get a set of roller rockers with the new heads anyways.

Thanks!!

The TFS 215 and AFR 205 would be very similar from idle to about 4000 or 4500 rpms and then the TFS would start making more power, probably around 15 rwhp, maybe more depending on cam. In your case with a mild cam, I'd expect 10-12 rwhp. Basing my opinion on many many builds I've seen and my own 402 build. My 402 started with afr 205's and after swapping to TFS 215's gained 29.xx rwhp !!! See link in sig for back to back testing and baseline numbers. No opinion on the PRC or ETP, maybe someone else can post personal experience. Good luck.

For the money it's tough to beat the AFR's for a mild 346. Excellent street manners with great low and mid range power. The TFS are good as well and will make more power on the top end but do require the rocker wher you can run your stocker with the AFR's . I know you said you might be getting a set of rockers anyway but your talking about $500 difference in the price of the TFS with rockers vs the AFR without rockers. Just an option to look at.

I sell them ( AFR) for less than what you have listed for as well.

FYI I offer both AFR and TFS as well as WCCH Edelbrocks (which you should look at as well) as well as others.

i dont think any of those are a bad choice, all are very well proven..

AFR

I dont see the Torque numbers as high with the PRCs.

I see cars set up like mine with about the same RWHP, but RWTQ much less when AFR heads are not used. I havent monitored ETP or TFS RWTQ

I would talk with AFR on the 215's they have coming out as well.

AFR 205's flow 298cfm @ .600 lift, PRC heads 5.3/ls6 heads flow like 312-3 cfm @.600 lift and cost less

TFS for the win!

If this is going to be a street car, I would go with the AFRs.

How do the mid-range numbers compare on PRC vs. TFS/AFR? Just because they flow more at .600 lift doesn't mean they are going to make good power under the curve. Also think about the exhaust side too.

yeah, i actually have that issue. but i would like to see with the new PRC 215 in the mix as well and some quarter times. but i could only imagine the hassle.

Despite my porosity issues - which are now resolved.......I'd go the ETP215s again.

In saying that, however, the AFR205s work well and are direct-swap, no pushrods / valve angles to worry about.

Are they still producing the ETP215s? I thought they ceased production.

cheers,

PRC is the best bet IMHO if money is the issue. They flow excellently and give very good results. Don't bash them, they are better than the most....

ahh the head wars continue...

It's about more than just a flow number. We've seen those lesser flowing AFR heads produce faster mph time and time again than a head flowing as much as 15cfm more than it. Read the sticky.


This guys was looking for a mild street 346 build with a 226 cam.
