I feel TPIS has some great quality on many of their products but I personially would go a different route on the heads.
Not that their heads are garbage or low quality but we have quite a few sponsor's who specialize in heads and produce a better product.
I have only seen 2 sets of TPIS heads used and wasn't impressed with either combo.

tpis is a sponsor.
I haven't seen any stage 3 stuff.
Last setup here locally was a 347 solid roller setup with a 256/260 duration cam through a M6/12 bolt with all other bolton's and a stage 2 ls6 head.
Compression was just under 12.1 and it made 440 after a full tune.
IMO not the results you would expect.

What price are the heads your looking into?

Kind of yes. I am just trying to get an understanding of their heads as their website sucks. I am F/I so really velocity is not as important as a N/A car. I got a pretty good deal on them as long as they were advertised right.
