I know nothing about them, nor alot of other stuff. And expect me to start posting alot asking about stuff, need to learn.

Soon i will get some and i am looking at the AFR 165's that i hear alot about but i saw AFR 145CC street heads? What does the CC stand for? and they are much cheaper. It says bare heads, no porting and no parts. And what is a stud? it deals with the rocker arms right?

 

I have never heard of 145 heads... I think there was either a misprint or a misunderstanding. AFR makes a 165, a Comp 165, 185's, maybe a comp 185's, 205's and 225's.

on the list at the bottom you will see what im talking about.

 

Thats interesting.................

 

they must be **** since not many people have heard about them, but i dont know anything about heads and want to learn. what does it meen porting? and bare heads and all of that.

 

Is is a Head Flow chart link http://sbftech.com/index.php/topic,72.0.html that I saw once and saved it. There is some great info on it, a little technical maybe, but it clearly shows some of the differences out there amoung the choices.

There is also some really great info given here as well.

I'd chime in a little more ,but the main idea is to go for an aluminum head (saves weight/dissipates heat faster) and go for a set that allows more air to breath through the engine.

Both (weight reduction, better breating) are the best power adders you can buy.

Great luck to you,
Ivan

I guess that the moderators blocked out the link...I dunno??..?? Try this http://sbftech.com/index.php/topic,72.0.html

Dead link there too, I'm sorry. It's not letting me do it. Sorry..

 

When they "CC" a head, they measure the amount of volume in the combustion chamber. The volume of the intake/exhaust runners are also rated by volume.

 

Thanks anyway Karma.

So the higher the CC the better airflow? Which is why the AFR 165 CC Street Heads are good? Larger airflow?

 

CC = cubic centimeters. When theyre talking about cc's, its how big the intake runner is (when referring to 145,165,185). Obviously the larger the runner the more air/fuel you can get in to the cylinder.
Bare head = no valves, springs, retainers, keepers. As for the studs, studs are used to mount your rocker arms. Ford typically uses a bolt down fulcrum (fulcrum- basically the pivot point of the rocker arm), where as a stud is screwed or pressed into the cylinder head and you would only use a nut to hold the rocker down.
-P.

 

Very helpful man. So bare heads aren't really that good to get? Or it is in some cases?
