3B/ABY/AAN 20V head required for project

[220bhp]

I need a 20v head for a 3b project,3B/ABY/AAN.or would consider 7a. it must pressure tested and crack free.With or without cams

[220bhp]

Anyone know where I might get one, it would be much appreciated.

i really doubt that you will find one easily that does not have any cracks.Best chance is to get a 7A one and modify it.

keep looking at meckisforum.de on the for sale section (angebote),since there are usuall lots of stuff there

You'll find heads I don't thin you'll find 2nd hand one's pressure tested however unless they are high end ported rebuilt stuff.

Speak to Spink and Acidburn see if they can locate a 7A head.

[Acidburn]

as jamo said I know of a few, i'll find out a price and let you know ok mate

Will most likely be a 7a converted over to s2 spec which means crack free

Raymor is selling one with his 2.5L stroker kit... See the FS section...

Out of interest, what is the difference between S2 and 7a heads?

[Acidburn]

7a - lacks the water manifold channels and fitting, also if its for the aby setup then the sender at the front is missing but can be fitted on easily enough. Also some of them don't come with sodium filled exhaust valves.

3b - most likely starting to get small cracks in the head as most i've seen have, 7a's are fine as they don't have the same sort of stresses.
