You may want to measure the size of the valves as they definatly looked bigger than yours IMO

Looks like a standard head to me too! If there is 28cc in them chambers they certainly don't look it.

If something is worth doing, it's worth doing half of.

how do you accurately measure CC's though? lol!
the chamber size is from memory


valves through the centre edge to edge
3.5cms & 3.1
thats how you measure them right? :S

carbon through between the valves do make them look abit smaller i guess and im no pap :p

anyone local to me that fancy measuring both for a beer? :)

This is a 28cc head:



The difference in the chamber shape is obvious.

Get some pictures of the ports up. Pref with a bit of light down them.

You can see the casting marks on the chambers and the shrouding around the valves.
