I plan to use this 2.2 head fitted with 50mm Imotec inlet valves,
unfortunately this head has gigantic chamber volumes (64cc...),
so I needed quite a tall piston dome to get a decent CR.
valve notches were cc'ed to be 4.3cc
dome volume was calculated to be 12.7cc
using a 1.5x98mm headgasket CR will be 11.2
fair enough for this crappy rod ratio CIH.
