Will L92 heads and L76 intake (w/fuel rails, injectors and TB) work on an LS1?
I have a 1998 Z28. My plans were to get a set of CNC ported LS6 cylinder heads (these: http://www.texas-speed.com/shop/item...d=649&catid=20) and a Magic Stick M4 cam (239/242 on a 112, maybe 114) to produce around 420rwhp (did more than that on my friend's car, although he had a FAST and I'll only have a LS6 intake, he had long tubes I have mid-lengths with a 4" muffled. My other friend hit 450rwhp but he has a M6 and LT's where as mine is an A4)...
ALTHOUGH, now that the L92 heads are on sale for $375 a piece assembled they are even cheaper that the texas-speed deal, have bigger valves and flow a little better... Can I put the L92's (part number 12582713) on my LS1???
I know they say you need the L76 intake (part number 12580123) with it but that's fine because for $475 you get the intake, fuel rails, 40# injectors and a 90mm TB... (all of which open another can of worms for compatability).
SO here's my questions:
1) Will the heads bolt up to my LS1?
2) Are the fuel injectors compatible with my electronics?
3) Is there a way to convert the electric tb or do I just try to find a manual TB with the 4-bolt pattern OR make an adapter plate for a F-Body TB?
4) Finally, would I be better off just sticking with the original plan (LS6 intake, LS6 CNC ported cylinder heads w/ M4)???
Thanks in advance, I'm a noob on this one!

P.S. Please don't "search" flame me... I did a search, I see others are excited about this setup and want to throw them on the 402 strokers but I saw no info about compatability with an LS1... thanks!

Unfortunately the L92 heads, from what I've read, will not work on an LS1 because of the small bore. I don't think they will work on a stock LS2 even, they require a pretty decent sized bore unfortunately.
I'd love to build an L92 based motor, but I think I'm just rebuilding my LS1 this winter for nitrous.
Go with your original plan, sounds good to me.

You also answered the next question I was searching (will they work on an LS2)

Look here...https://ls1tech.com/forums/generation-iv-internal-engine/590534-sdpc-402-w-l92-l76-begin.html
The 402 has the same bore as a stock LS2.
