dave that dont make sence, if the head looses its squish areaand its not taking into consideration it will make alot of difference
if the engines being built and the ultra skimed head taking into consideration and other things looked at ( not spacer plates

) then it dont make a difference
providing when in take my pistons out there not fooked then im not gonna change mine at all or skim the head ( well i cant as the valves would open and show the engine bay

) as theres no det on my head at all and as i ideally need a new head im gonna stick this back together and fizx the problems i had with the engine and then im gonna buy a brand new head and have that sorted then rebuild it proper in the winter ( if i feel i need to

)
any news when ya cars gonna have the engine fitted ect
