What would you do??

[GeoffP]

What would you do if you had approx $2000 to spend on an engine build up and were torn between buying TFS 23 degree heads for $1000 or AFR 190's for $1250?? Which head would you buy and why? In my little bit of research, the AFR's outflow the TFS heads by about 10 CFM at .500 and above, but neither has much flow difference betweeen .500 and .600 lift. Opinions are definitely welcome!! smile.gif

I spend the extra for the AFR's so ya dont have to mess with the modding the rockers, push rod length and other weird crap that goes along with the TFS heads.

That's the good thing about the 23 degree head over the twisted wedge head...you don't have to do funky things with the rockers and such, though I probably will buy special length pushrods either way I decide to go.

AFR's, they have thicker decks that are safer w/ nitous or artificial boost. AFR's flow better where most of your street driving would be as well.

[GeoffP]

So we have 2 votes for AFR's so far... BTW, Kat, I haven't gotten any reply from my messages to you about the STB. Please e-mail me.

Thanks

Well I haven't seen anyone that has actually gotten good numbers using the TF 23' heads....although i haven't looked.....right now if I was set on getting a TF head it would be the G2's , trouble or no I've seen some pretty good numbers rfom people using the twisted wedge stuff and these ones solve some of the durability problems found in the G1's.....but when it comes down to it, I'd get the AFR's....last set of heads you'll have to buy unless you go a lot bigger engine later on...then you just need some bigger AFR's....;)

I agree Tom...AFR's would be the last heads I'd ever buy. Actually either will probably be the last I ever buy seeing how hard it was to get the money together to do this project correctly. At this point I'm still undecided on what to do...hoping to see some good info posted here tonight for when I come back to work in the morning... ;) Thanks for the reply Kat! I'll be waiting for the payment and will get the STB out the door that day or the following...

So I guess the question with AFR's would be "Which ones should I get??" 190, 195, or 200? I know when I called AFR in the past, they suggested 190's but that was a different engine than I'm building now and a long time ago...

For a 383 I'd get the 220's but thats me :D All the power is in the heads smile.gif But if ya want a extra few dollars to spend on some roller rockers new push rods yadda yadda yadda I'd get the 190s

As fer the STB I sent it out today with 2 stamps on it.. Wonder if that will make a differance. :shrug:

AFR makes quite a few SBC cylinder head choices; 190's, 195's, 210's, & 227's. The 210's & 227's are listed as a "race head". I have the 195's for my car which happens to be a 6" rod, 383 w/ a Mini Ram. If I remember right, Geoff - you are sticking with a TPI set up right? I'd go with the 190's or the 195's. I have a much higher RPM cam & intake and the 195's are plenty. I'd have to go with a different style EFI unit and a solid roller cam to need the 210's. The 227's would require a bigger motor all together.

The only reason I ended up with 195's & not 190's is because my father had already bought them for a supercharged 355 he was building. Somewhere along the line he sold the blower and needed a set of heads that would raise the compression ratio in his motor to run it NA. I just happend to have a new set of ZZ4 heads w/ 2.00/1.56 valves sitting in my room. We made a deal & my 355 TPI build-up snowballed into the current 383. I see quite a few cars with the 190's making good #'s on the dyno.

I'd save a little more and install and used LT1/6speed combo tongue.gif graemlins/hump.gif

[irocbsa]

I'd go with the AFRs too. Ahhhhhhhhhhh... AFRs. <drool>

[SportCoupe]

I'd get AFR's if I was to do it again. Main reason is they will drill the head for any intake pattern you desire. I would have them drill the head for a LT1 intake bolt pattern. That would be cool.

[Pantera61]

The TFS heads are awesome, from experience. My friend had them on his car and they are bad mambajambas. I don't know which flow better, but I would do a search for both. Why not TFS 18* heads?

[LL6]

If you use 18° heads then you need an 18° intake. Haven't seen any of them for TPIs. :(

[GeoffP]

RobP - Already did the LT1/T-56 combo...I had an 83 Z28 with that setup. smile.gif Very nice..

I still don't really know which way to go...I appreciate Pantera's input on the TFS 23* Heads. I'd love to have the AFR's, but the $260+ price difference will buy a 52mm throttle body or quite a few other needed parts for the build up.... Hmmm...what to do....

[86305]

If your looking to save a little money then get the tfs 23's. But get them from here.

I thought since Summit owns TFS that they had exclusive sales rights on new TFS product? Can you enlighten me on this? Thanks!
