I'm raising the compression ratio by facing the head on my celica sx (ST162) and I was wondering if anyone can tell me how much volume (cc) there is on, or kind of in, the crown of the piston seeing as there are small indentations corresponding to the valve placement. Sometimes replacement pistons have these details, but seeing as I don't need any replacements, I was wondering if anyone here knew.
I don't necessarily need this information, but it might help make things a bit more accurate (calculations need to be made sometimes as much as I don't like 'em)
