For the money and performance differeence sounds like your head is still a better deal.

You are saying no core is required... but If I do give you my good core - how much would you deduct ?

How much would someone buy an extra head for? I have one sitting at my house, one bent valve, otherwise it is prestine.

interesting, is it ported here in the USA?

i'd love to see a ported head shootout between Buschur, AMS, and cosworth

Does it come with rockers and lifters? Cam sensor assembly?

I dont believe that they offer any kind of a core charge refund.

we are outfitting this head on two cars that are getting very similar builds to that of Chris' black evo. The proof is in the pudding. we will have to see how much better they really are

So you reccomend this head for what? Turbo size of over a GT35? 3076? 3071? just thought I would ask, as I know someone else besides me is thinking the same thing!

uh dude I don't know if AMS is better... I do know Cosworth is a big name with a big rep ur paying for the name and their expertise.
I want head too ****

The biggest selling point to this head other then the fact its CNC ported is for guys that dont have a good core to send in. The core charge on an evo Head is about $1600 and on top of that if you add in an Inconnel AMS Race head you are looking at an extra $2100.00. For about that same price you can just outright buy the Cosworth unit and not have to worry about shipping us a core.

Our machine shop is great at porting but we dont have a nice CNC machine here for porting. its really hard to compare the two.

This head doesnt take anything away from the AMS race head. Its just another option we are offering the public.

Cosworth is a great company and im sure this product will not disapoint.
