Does anyone know of a site that compares ls6 stock heads to other aftermarket heads, ie flow numbers, dyno numbers, etc...

Thanks in advance

GMHTP just did a comparison between aftermarket heads on an LS2. The base numbers used the stock Ls2 heads which are basicly LS6 heads.

Livernois just re did their heads right after that too... guess they are flowing much better at the same price as before... just a fyi.
