Just as the title states, i bought some used afr 205's. I was told they have 5000 miles on them, just wondering what i should do to them before i put them on. I thought maybe valve seals would be worth doing. Anything else??? Which of the sponsors carry valve seals for the afr's??

 

Personally, I would have them freshened up.

 

I'd definetly send them into Tony at AFR to be freshened up, valve seals and thier upgraded 8019 spring. This would also be a good time to get them milled.

 

What do you guys mean by "freshened up"?? I was actually going to take them to a local machine shop and get them milled a little more, theyve already been milled .018 and they have almost brand new patriot gold duals on them.

 

Before having them milled again you need to verify how much was originally milled. Freshened up simply means going through the existing parts and replace as needed to make them like new. As mentioned above, contact Tony Mamo (user here). He's redoing my AFR 225's right now (alot more than freshening up ).

 

At the very least, lap the valves and check spring pressures and installed heights. Replacing the seals is a good idea since you have it all apart. GM sells seals, as well as a place called U.S. seal, which is cheaper I think. You may want to have them mill a cleanup cut, to make sure the surface is nice and flat.

 

How much did you pay for the used afr head if you don't mind asking ? I am thinking of buying same heads this weekend it has 13000 miles for $ 1700 .

 

i bought a set from someone off this board for 1650 shipped. I think i got a good deal!

 

I guess it all depends on the individual. How many miles were on the head?
