I don't think you'll see us building a carb style intake anytime soon. The heads are coming along very well, I expect we'll have them in stock pretty soon & pricing should be very attractive!

This head isn't the same as the other heads your discussing.
The PRC head is a functioning LS7 tweaked to run on a slightly smaller bore. It's not something where we had to go to a tiny valve & take most of the LS7 benefits away to get it to fit a 4" bore or something smaller like that.
This head was built for the 4.060"+ bore guys using LS3/L92 blocks & wanting to get the best possible cylinder head configuration.
I don't know if I'll do a smaller bore LS7 head, at smaller bores the LS3 PRC aftermarket casting head becomes a better option.

it is my mistake when typing while sleeping...
I meant to say LS3/L92 for 3.989" bore engines, which now mast and GMPP is already done big move on it.
I saw on the LSXtv.com that TFS have showed their LS3/L92 but I think it is for 4.000" bore
But TSP is pioneer in LS7 to be fitted on 4.060" bore...
Thanks...
