I've been seeing a handful of manufacturers making these small bore ls3/l92 style heads. Very cool stuff.

Toss me a free set and i'll plaster a huge "Ballistic Speed Parts" sticker down the side of my car....

Haha...I'd love to man!!

Yeah there is not many options for this setup, the GM version only flows about 280 cfm and the Mast version is $$$, so we're trying to offer a very powerful and more affordable alternative.

We used a custom spec 248/259.  All of our back to back testing was done with a stock Ls1 block and we used a shelf grind 232/239.  Yes, stock Ls3 intake manifold with some mild cleanup work, we'll probably do some testing with a Fast 102 in the near future.

Yeah GM's CNC Ls3 head flows well, the GM version I was referring to is their small bore Ls3 head which is as cast only and flows around 280 CFM.

Chamber size starts at 70cc.

Curious as to this as well.  Has anyone installed these small bore stage 3 heads on a stock displacement cammed engine?

Normal LS3 heads work on an LS2. Why did you mention them in your list? Also did I miss the pricing on these?
