Ported AFR 190 57cc LT1 heads.

They were sold and shipped to a member of the board and he claims he took them to a "speed shop" and they said that the scratch marks (made when the valve seat material chip was dragged across the alum. by the cutter) needed to be removed. I refunded him and paid for shipping them back. I and everyone I've spoke with disagrees that they will affect the heads! I work in a machine shop and everyone here has looked at them. I have included a pic of the scratches. 800.00 shipped

 

 

What kind of springs are installed??Wondering if they will work with a comp 306 cam?

 

To tell ya the truth Im not sure I do have another set but not sure on them either. I have had this stuff for going on 10 yrs now and no longer have Camaro.

 

Is there away you could find out a part number on the springs?Do you know what brand they are?

 

I have know way of knowing what springs they are, they are dual spring with damper tho.

Excellent heads and bump for you as I have those same heads on my car going on 12 years. If they are the AFR springs they sent with the heads here is the specs:

AFR #8020 (dual)
1.450 OD, 120# seat and .550 max lift

They should work good for the CC306 cam, however I upgraded mine to the following springs after I got a custom cam from LE and he recc'd these:

Howards Springs #98441 (dual)
1.437 OD and 135# seat

Good luck with the sale.

ttt price drop

 

This may be a stupid question, but would these have any effect on a stock LT1?

 

I would think they would work fine ya might want to upgrade the cam too tho to see more gains. Ask the guys on the board!
