hey all, Ive got 853 heads on my stock 1999 A4 trans am. I'm putting headers on with dual exhaust, and just wondering how these heads rate as far as flow on a dd . thanks for your input.

They are just your stock run of the mill heads....sorry. Ported they are pretty good but if running OEM heads I would have AI or TEA port a set of 243/799 heads. They are simply better and can make a lot of power and are a a good bang for the buck IMO though not the cheapest OEM heads out there.. Get your basic bolton's done first so you can best support the heads/cam later and whatever else you wanna do.

Since you are a a4 a stall is the best mod out there for you right now and will be needed if you wanna run any decent size cam anyway...

Edit: A stall will negatively affect your in town MPG though but locked on the hiway will be the same...
