Hey, I was looking at buying a set of AFR's 195 Heads... Here's my setup as of right now: -74' 4-bolt 350 (bored 0.030 over) -Keith Black pistons (normal compression) Basically a stock bottom end other than the oversized pistons. -Edelbrock Performer Intake -Blue Racer Camshaft (224 at 0.050) -670 Holley Street Avenger Carb -HEI w/ Accel Supercoil -14" 1 3/4" Element Air Clean (think its killin' me) I think i've got a good setup but i'm still not happy with the performance its putting out. The heads I have are stock 1974 heads. Not the double hump or nothing, just plain stock. Would adding the AFR heads give me a big hp increase and noticable acceleration or should I save the 1000 and try something else?!?! Thanks

Get the AFR heads,you will not be upset.You will see a big difference over your current heads and combo.Also get a taller air filter to gain airflow,but you already know that.What is normal compression ratio?try to keep it around 10:1 for good streetability on pump gas.

AFR is the best! Another good head is canfield they are much better than my old vette heads.

They put AFR's on a TBI 350 truck w/ 1.6 rockers and got 55HP and 58 ft/lbs of torque at the tires. I think that says good things about their product. Plus, I am a proud owner of a set of fully ported 195's.

Definatly go with the AFR's. but swap to a performer rpm intake when you do and youll pretty happy with the perforamcne

thanks for the info guys, now i need to get them bought while i got my 0% interest rate on the card for 6 months
hehe

Also...to further compliment your AFR headed set-up...a little more carb would go a loooong way. try a 750 and you'll see a big difference as well

You guys really thing the 670 is too small?!?! I kinda thought of that. But would a 770 be too big?!?!

There is no such thing as a carb to big, just an enigne that is to small!! You could set the 770 lower if the engine is to small for it.
