Re: lowering compression using headgasket? (crxvtecturbo)
Yes it can, cometic also makes a thicker hg. I beleive for every .040" thicker is ~1cr lower. At least this is what the people @ cometic say. So a stock hg is .030" and another .040" would make .070" which would lower the cr by ~1.

Re: lowering compression using headgasket? (JDM00SI)
why is it that those headgaskets require the use of adjustable cam gears?

the gasket is so thick that it raises the height of the head enough to throw off the cam timing. adj. gears are needed to get everything back to where it is supposed to be at TDC.

yes. cam timing refers to when the cams open the valves. ignition timing is when the spark plugs fire to ignite the air and fuel mixture.
