Any pics of the ports on the 806's? Centerbolt?

 

I can take pics. They are perimeter.

 

they probably flow around 295 at .600

if your switching to L92's does that mean your running a 4.00 bore?

 

I always get the 806 and the 853 mixed up.

 

853 is the centerbolt.....so they are the ones we need new valve covers for correct like on the 98 model years? are the ported 806's still for sale? What springs and retainers they come with?

 

Ported heads are sold.
