They do what you might refer to as "assembly line" cleanup behind the valves, to blend the casting to the machined seats...and it flows 238 at 28"...out of the box. Maybe that's all it's gonna get, but it would be the first head ever that couldn't be improved.

I don't care what some of the wanna-bee head-hackers on here say, you ain't gonna get near this head with an iron casting, the port has been moved out to where there's only H2O in an iron head.

thank you for the clarification, its awsome to have guys like you in the community that are willing to spend the time to help out with this kind of info

so u can put the arca head on a turbo car? :tfrules:

[Turbopit]

Yes, why wouldn't you be able to?

[deuce2583]

sweet i really wanna get one but im poor, guess i need to save for a while

[Turbo_Dude]

Yea the esslinger d-port head is 1500$ ready to bolt on that quite a bunch but i will be getting the svo head pretty soon for my car

[sprayed65]

Im curious as to what accessories the head holds? :headscratch:

when I did my motor the alternator/power steering bracket bolted on the block, the small aluminum piece that the alternator bolts to on top went in the head I think but Im sure it would be easy to fab something else up to hold it in place, the a/c bracket on the other side of the motor also went in the block itself....maybe I am just being silly but I dont see really how the d-port is any more of a bolt on other than maybe being able to use a stock cam if you wanted to? and the stock intake/exhaust manifolds?? for someone who was really going after some kind of hellacious power I would think maybe one of the other choices might be better as you'll be using some sort of custom intake anyhow and likely some sort of custom turbo header

someone correct me if I dont know what Im talking about
