906 heads?

[TXcharger70]

Was wondering if this is a good deal or not I want to due some engine mods to my 383 and saw this ad for "Ported 906 casting heads. Milodon SS valves, Comp Cams HD springs, retainers and locks. Fully ported intake, exhaust with pocket and bowl work. Fresh valve job, never been run" for $750. I am looking to add some performace to the engine since i have it out and it is in the body shop. I am in the process of breaking it down to see what kind of cam it has from the previous owner. Or should i get eddy heads since that is what i see most people running

Depending on how much "porting" has been done, you will loose some HP & torque on the lower end, but will gain it back on the upper RPM band...(if job was done correctly)

I got ported 906's on the black car...port job was over-done...(more ain't always better)...I lost a lot of lower end...but above 3500, engine comes alive.....

I'm looking for stock heads now to put back on...

if you are not going for the stock look,i would not spend any money on cast iron heads.look into some performer rpm,s
