Guys remember lots of boost can make up for a lot of things.... Boosted numbers only relate if you have the same psi level, type of intercooler etc....

What you should really be looking at here is the differences between the two heads and what you need.

The big advantage on the 210's is the thick deck surface it has vs a stock casting. That is going to help keep the head on the block and not lift under high boost.

BTW I just finished up with a 352 cube turbo build and it has a set of AFR's on top of it.

You can always do the combination and have Lloyd port a set of AFR's for you.

I'm pretty sure that the $1300 would be complete (porting, valve job, milling, valves, springs etc...)

Exactly. I chose the AFR's because of their flow capability (flow much more air at lower boost levels then ported stock heads) and for their deck height and combustion CC's. I had Lloyd port them for me since I was happy with the stockers he did 2 years ago. I would definitely think the 1300 was complete and ready to bolt on as well.

My local guy is cleaning up a set of AFR 210's that I had bought that were originally ported by a shop in Texas.

I will have around $3K into the heads when they are done and the results are pretty decent:

AFR 210, 2.19/1.62

LIFT---INT--EXH--I/E%
0.200--168--112--0.67
0.300--222--151--0.68
0.400--262--206--0.79
0.500--289--218--0.75
0.600--307--232--0.76
0.700--311--246--0.79

These are the results as of 1-1/2 weeks ago. He left a message telling me that he has gotten even better numbers at every point.

I had a set of AFR 220's and my AFR 210's flow better all over the place...but I am sure with the same work, the AFR 220's would nudge them out.

Some local shops can sometimes do well...

a 2.19 intake valve?!?! WTF??

what size motor is this going on?

JustNO

My 210cc competition Heads have 2.08/1.60 valves.. (its 383cid)

I have a set of AFR 220's that are going to Lloyd. I'm going solid roller so I think shaft rockers are in the future for these heads. For an N/A motor you need to take into account the displacement and how high you're going to rev before picking which head is right for you.

Why do you send your heads? porting or valvetrain ??? I don't understand why people don't to porting at AFR.. AFR is a bad porter??

Let's just say they are not nearly as good as Lloyd, AI, or any other reputable porter.

Do you have proof??

Call here and see what the answer is to the question,"Does AFR have a HAPPY flow bench".
www.proheads.com
I know his porting will outflow AFR's.

jnjspdshop

I am sure proheads is completely non biased because they don't sell ported heads

Flow numbers are nice to sell cylinder heads, but they are just like dyno numbers. We don't race flow benches or dynos, we race cars.

Fact is some of the fastest SBC, LT1/4, and LS1's run AFRs. Yeah there are other heads that are as good and some that might be a bit better however AFRs consistantly are on top.

My buddy paid alot of money for his comp ported afr 195 LT4s. They were very rough and flowed quite a bit less than advertised on a superflow bench with a stock size bore. He changed from a 306 cam to a Joe O grind and had Eric Bradby clean the heads up. He picked up over a full second and 5 or six mph I believe in a convert.

DiabloGT

does everyone think dart pro 230's are better quality than afr 227's? if both fully ported from ai?

Ram Air 9C1

Get AFR ported heads flowed by an independent shop and compare their flow numbers with AFRs. I've seen people pick up 30+ rwhp by doing additional porting to AFR 210-220 competition heads.

I know ya didn't go to that sight and read.
West Coast Cyl Heads IS a head porting shop and that's ALL they do.
Wasn't talking about AFR castings The question was about their port work.

So ya can comment all ya want without reading,seeing or talking to someone that KNOWS head porting.
