CMS/MHS Stage 2 heads

Im considering the stage 2 heads from CMS/MHS and was looking for any advice about them. Specs are in the link.

MHS/CMS 2V Head/ Cam Package - Stage 2 [MHS/CMS2VS2] - $2,275.25 : Zen Cart!, The Art of E-commerce

Basically, Im looking for any imput regarding what kind of gains I would be looking at with these heads with:

a.) stock cams
b.) stage 2 or 2.5 CMS/MHS cams

Current mods are CAI, Accufab plenum, Accufab 75mm TB, stock exhaust manifolds (for now), off-road midpipe, catback, 4.10's.

Thanks.

I would LOVE some TF heads, however they're too far out of my price range. The TF's run about $1000 per head and are essentially bare heads. CMS/MHS is offering a fully built head AND cam package with my choice of cam professionally built (w/ rockers, upgraded valves, fully degreed, etc). You simply unbolt your stock heads (with cam) and bolt on the new heads and cams. I would save a BUNDLE in labor (cheapest quote for installing just cams alone was $750).

I could have stage 2 ported heads with upgraded valves and spings, degreed stage 2.5 cams on the car for around $2500 including any labor. I'd be looking at roughly $3K for a pair of TF heads installed with STOCK cams. Seems like a no brainer to me.
