" Sounds like you need to install Firefox with Adblock.. problem solved. "

____ Actually,, I use Firefox-12 (which is the latest version which will still fully work with XP-Pro sp2). _ But I don't have problems with general-net.pop-ups, but rather just with some unknown ad that Netzero-itself runs on their-own pages (as they recycle various ads on the side of my email-page).




" does the larger compression number mean larger valves required? "

____ I only included the added info on pistons, for general readers to take-in,, so as to make my post more relevantly worthy of having opened for a look-see.
__ Those who are already well aware of cyl.heads with either 'small' or 'large' valves, probably realized that my wording indirectly addresses the subject of your question. ...
Anyhow,, the compression-ratio and valve-sizes are rather independent of one another, and-so either could be combined with either !
__ Most-USUALLY the small-valve heads are combined with low-CR.pistons with correspondingly small valve-pockets, and large-valve heads are combined with high-CR.pistons with correspondingly large valve-pockets.
So therefore I thought it noteworthy to point-out that the ASSO-pistons are rather conversely combining low-CR with large valve-pockets, AND that the high-CR.Mondail-pistons rather sport small valve-pockets (which helps the Mark-III10:1-CR be as high as it is, [while the large-pockets of the Mark-3 piston-model consequently lowers it's comp.ratio down-to 9.8:1] ).
____ Anymore related newbie-type questions ?
