Anyone have Frankenstein stage 1 243 heads?

I'm interested in their heads on a ls1 as well. I would really like to see how their tfs casting heads do. It seems people these days put cheap heads on iron 6.0's and no one spends any money on the lil ole ls1 any more

It sounded like you were looking to "get results", as in get the right parts to get the results. You are looking for "reports of results", just to clarify.

STOCK VALVE 243 HEADS
I have been researching 243 heads for a couple of years, constantly going back and forth between AI and TEA for the best all out heads, and Texas-Speed (PRC) as the best bang for the buck.
For stock valve size, Frankenstein heads are right between PRC and AI/TEA. What I find intriguing is that Frankenstein uses a smaller intake port than any of those three, AND they have higher flow numbers from .2 to .5.

That's really interesting with the smaller intake port. At first I missed that these have the stock valve then realized it later. So for all competitive purposes it sounds like these would be more along the lines of the PRC stage 1 243's, but with the smaller intake port from what you're saying
Also, they port match intakes, which I do not believe Texas-Speed does.

There is very little difference in flow between the TSP/PRC Stage I and Stage 2.5 due to the ONLY difference being the larger valves on the Stage 2.5. The porting is identical between the two.

Yeah, either stay on topic or the OP will come down on you like a (wait for it...) Big Hammer.
