E88 head; off 1983 Skyline 2.4E

Took this head off a motor recently given to me by a friend. Motor wasfuel injected L24 off R30 Skyline.

Apparently this version of the E88 is better than versions found on early Z's and various other models.

I want to get the chambers CC'd, can't find info on them but I'll be topping this off on my L28 w/dished pistons, apparently a nice C/R of around 9.2-9.3:1. Looks a lot like the P90/P79 heads raved about also.
