Re: Best pistons for vortec heads

[QUOTE=Billla;2610386]I'll respectfully disagree with a few of these comments. Compression height is 1.560; the only reason for a "shorter" piston is to compensate for a significant cut to the block deck. If the piston is at anything other than .025 standard deck height (block deck of 9.025) then someone ordered the wrong piston.

Thanks for the correction. Although I don't fully agree. It's the "stock production" cheap replacement cast pistons that production shops use and push that all seam to be destroked. This is to compensate for deck surfacing to maintain close to the standard .025 deck height. Again I'm talking about "production shops". I find that not all shops surface decks and if so only a clean up pass. This is what I was referencing to. So many people go in to a shop and have a engine built and come out with less compresion than they went in with.
