Anyone tried both TFs and AFRs? am looking at an AFR 190 vs TF G2s seems that TFs are 20% less than AFRs and make similar flow numbers.

the AFR 180's flow more then the trick flows 195's, so more tq and more hp out of the AFR's, but then again I might be biast

I run the TFs and I like them. That said what are you putting them on?

Hawk92z-TDZ

ya I have a used set of trick flows sitting on the garage floor, they werent a bad head, defenetly better then the edelbrock and such, they would defenetly be my number 2 choice

Its only a 305, honest Wanna race?

SO for the mighty 305 with the ZZ4 cam. Should "The Project" run the TFS or the AFR's?? Bear in mind compression loss with the AFR's.

305 has wrong bore size.

if I was keeping the 305 (which I have done before on previous cars) the lesson I have learned is don't do heads, put money to a Procharger instead. Make sure the air flow in and out is excellent and make sure you have a decent cam.

There are 6,876,213 posts telling you the 305 is the wrong motor to build. do a 350 instead. Guess I am number 6,876,214...

palric

naturally I have to ask -- how much for the used heads?

Hawk92z-TDZ

Even thoguh i'd suggest building a 383 or bigger (350's are for chicks) just kidding

If your stuck on a 305, trick flow does make a specific 305 head, were as the AFR's are for 350's and up, the valves are too big on the AFR's for a 305 with the lift of a zz4 cam. AFR used to make a 305 head, but its been long discontinued

Hawk92z-TDZ

NFS, sorry, not sure what I'll use them on, but no sence loosing $ on them when they are still a good head

They ran 12's N/A bolted on a 406ci in a Monty Carlo with a Magnum 292 cam, so as I said, not bad heads by any means, I just find/like the AFR's much better
