cylinder head cc's ?

[rex-leggy]

has anyone ever measured or knows the cc volume of v/3 wrx heads?or is there any record of anything hidden away that i cant find with the search.

i need to do some cr calcs.

what i know so far is that with

2.2 block , 2.5 crank , 2,0 rods , wiseco 2.2 hybrid pistons ..... with 2.2 sohc heads with a 46.6cc volume i get a cr of 8.5.1 (i have the other variables)

if someone knows the volume of the ej20 heads i can figure out what needs to be done to my heads to keep the cr within i spec

well if i go off of what that chart says that a ej20 v/3 head is 46cc volume and the sohc ej22 is 46.6 then my cr should be sweet or close enough not to worry about.

just wanted to find out as much as i can before i got to the re conditioners and pay for the pistons. alot of $$ to spend just to find that i need to do machining to the domes or something like that.

cheers for the link koom some good info there
