what can you get these to flow fully cnc'd?

Google is your friend...

This will probably be moved

 

With many heads on the market today and even though I run AFR's., Most do not flow as advertised and AFR is one of them... expect independantly flowed to see 15-20 cfm less than advertised...Every bench is different it seems....With additional handporting however the numbers they do have on thier site is achievable!!

 

Buy them bare and then have them ported by an outside company the specializes in SBC (Esp LT1). You will get much better results. That is what I am doing with my AFR 210's.

 

these heads were bought as bare and cnc'd after purchase. the guy is selling them and doesn't want to say flow #'s until cash is in hand

 

To me that means DON'T BUY THEM!

Sounds like the normal rip off junk.

well the guy knows what he's doing. he built a 383 with these heads and it made 557hp and 501 ftlbs with 10:1 on pump gas.

 

Doesn't matter.

I suggest that you tell him that you have cash in hand and are ready to buy, but you want to see the flow sheets BEFORE you do.

Otherwise, walk away. Anything that sounds too good to be true generally is.

 

Ditto....

Is it really saving money if you buy junk?

BTW did these exact heads make that power? What were the parts run with them etc...

I know flow numbers don't mean anything, hell 260cfm Super Stock ports can make over 600hp with the right setup.

yes these are the same heads. he says it has a decent solid roller cam, didn't say specs until $$$(if i bought whole engine), all forged, victor jr. intake ported to match, pro form 4150 holley carb, 10:1, MSD pro billet dist, 5.85" rods, um....what else. i think thats all i know about it.

he built a guys 406 with canfield heads 9:1 and a smaller cam then whats in the 383 (he says) and in a 3200 lb 68 camaro at 4600ft ran 11.02 all motor. and a 10.3 with a 150 shot.

he runs a 323 sbc in his 3rd gen bird and runs 9.2's i think. all motor at 4600.

 

if you are defending him so much you seem to have already made up your mind. If he is a reasonable guy he will give you a reason as to why he isnt disclosing information.

 

If he's not disclosing the flow numbers, he's got something to hide. Heck, if I was selling a nice set of heads I knew they flowed good, then I would use that as my selling pitch, won't you?

 

i wasn't defending him just saying he knows what he's doing.

i've decided not to buy them anyway....so thanks guys
