2AB
Y86HF6090AA CNC195

thanks in advance

 

they do mean something, but i cant tell you what!

you're best of posting a few pics of it as i'll be able to tell you then what it is

edit: post a pic of where all the valves are showing, as you can tell by the waterways what head it is

 

 

thats a 3dr/ early saff 2wd head - you can tell by the 2 bolt thermo housing face on the front, later YBs had a 3 bolt set up

 

wicked cheers fella

 

as above; the later 2wd heads had a 3 bolt thermostat set up

to be honest that head dont look to be in the best of conditions mate; what's the deck height? looks quite bad around the waterways compared to the heads i've had

 

its very grubby at the min needs a good clean up . deck height from what i can remember its 139

 

if its 139 then you've done well; as they are only 139.2 from factory

i dont mean it looks dirty; i meant it looks quite pitted round the waterways; but its the valve seats area which is most important

get it checked for straight'ness make sure its not warped & get it checked for cracks with you cant see; also i'd recommend getting it lightly face to freshen the surface

if you're fitting a wrc gasket you'll need to get the block faced too

 

it is mainly just dirt and crap its been stored for a long while .its got a few battle scars but i bought it needing to be checked and a light skim.

im not 100% if im going to use it yet .i just cant turn down a good deal

 

we all like a good deal!

 

is the cnc 195 part hand stamped?

if so its a rick wood cnc head...

 

yes mate its hand stamped

rick wood head ?? is that good

 

mine cost 2.5k...

check these....

www.cncheads.co.uk


each head is numbered when its ported by them.

 

looks maybe it might be worth getting repaired then

 

if you rang rick and check what spec it is, then youl know what you have....

the std valve head is fit for 550bhp

 

lovely job i will give him a bell then see exactly what im working with .cheers bud for pointing it out

i thought it was a little odd as never seen one that had hand stamping on it . didnt think much of it thought to be fair lol

 

What`s the pen marks in the cahmbers of 2 & 3? Is it cracked?

 

That was the one of EBAY and i think the lad said it had cracks in it . CAN they be repaird ?????

 

the pen marks are highlighting a couple of marks and poss 1 or 2 tiny cracks.

it was sold as all being cracks just encase .

i will soon find out if it can be repaired when i send it off

 

Lets hope if they are cracks that they can do somthing with it as it would be a good find all the best with it

 

yeah hope so . tar fella
