from kuwait...so i'm guessing english is not great. so i'll try to help.
by mix-up i think you mean "build up"....for 430rwhp without doing heads.
that's not easy...but not impossible either.
you say its an ls6...i assume with ls6 heads (243s), which will help. you'll need a decent cam and all the bolt ons. something like the futral F15, TSP ms4, or the TR t-rex.
and to make sure you got full potential, i would budget in a FAST 90/90 on top.
should get you to your goal on stock heads...or pretty damn close

there is a guy, screen name 418redz28, who has 243 heads and a 232/234 camshaft with an LS6 intake that is making 430rwhp.
Im doing similar. Take to Patrick G, he'll set you up right!!
I would also recommend bumping your compression up a little with a .040 head gasket but unless you aren't planning on taking your heads off it might not be worth it.
teke184's advice will get you there and then some!! trex, 90/90, and 243 heads might get you 450+ (just a guess)

Well I'm also not exactly sure what the OP was asking, however, I have an LS6 CTS-V. Currently I have 380 rwhp with most of the boltons (kooks 1.75 headers, high flow cats, 2.5" duals, Lingenfleter CAI, smooth intake tube, Mamo Ported Fast 90, NW 90 mm TB & a dyno tune), on a mustang dyno [ https://ls1tech.com/forums/dynamometer-results-comparisons/822519-stock-head-cam-346-ls6-w-bolton-s-pre-post-fast-90-90-results.html ]. I had Patrick G spec me out a cam (224/228 .598/.619 111 XFI/XER). he guestimate between 40-50 rwhp, so I hope to be somewhere between 410 - 430 rwhp with just a cam, and stock 243 heads. I'm sure I could get higher if I went with an MS4 or TREX. I plan to add an Underdrive pulley when I put the cam on as well.

both are excellent choice of cam. I am a bit biased as I have the MS4 in my car, and I love it. I've seen plenty of people with stock 243 cast ls6 heads and this cam put down 430-440 on a dynojet so it is very possible with untouched heads. Just keep in mind that with any big cam, you will need to upgrade to better springs. All in all, you can't go wrong with either cam.

sorry, I thought you had the 243 heads. I cant think of any cam that can make 430 whp with the stock untouched 241 cast heads. I think the only way you will see those numbers is with the 243 heads or some aftermarket better heads (i.e.- AFR, trickflow, ETP, etc...)

in that case, than yes, you will definately make 430-440 whp on a dynojet with that cam (MS4) and heads (243) setup. With a ported FAST 90/90 setup, you can be 460-475 whp fairly easily with some good tuning. Good luck!

None of these cams will fit. Flycutting is now mandatory for any big cam. Flycuting is cutting eyebrows (reliefs) in the piston so valves don't smack them.
Being in Kuwait that is not easy to do, my advice, get some ported heads and match a cam.
As you sit now, 224 size cam might all you can fit underneath. That will not get you 430 but 400 is achievable.
I would say (if indeed .030 was cut) a 224/224 .609/.581 114+4 LSA would do the job with bolt ons.

LS1 heads 241 66 cc
LS6 heads 243 64 cc
if i mill the LS6 030 how much will be ? because some one said ( if the cam is too big, then you'll run a valve into the piston ) can i put MS4 ?

64cc -5cc = 59cc
There is no way you'll fit a MS4 or similar cam in there. each .005/.006 mill = 1 cc
