Yes it will. The extra weight should help it retain it's shape (no warping) and usually indicates higher quality vinyl in the pressing. They should be able to be played in any normal record player in addition to the high-end rigs they were designed for.

Try this site, here is an excerpt from the site, and its address:120-140 g is a "normal" vinyl LP, like most new releases in the 20th century. 180 g is considered audiophile grade and most new releases and re-releases available today come out in this format. The record is thicker and heavier so it may be less prone to warping over time. Some claim sonic benefits on 180 g's like better stereo imaging, less noise, wider bandwidth, etc. Another factor is "virgin" vinyl (often a feature hand in hand with 180 g and heavier LPs) which uses no recycled plastic which can contain impurities leading to a noisier record.* http://www.hometheatershack.com/forums/hifi-audio-components/3870-what-180-gram-vinyl.html
