I would think you could find some for $250-300 then have some room to get them set up and milled for a couple of hundred and your there.
I have seem some low mileage Vette 243's for $500 on Corvette forum. You would have to change out the springs which would add another $200.

I thought you already had to change springs either way to match your new cam...? Correct? Aren't you doing a cam swap as well?
I tried craigslist in Denver, CO and there must be a lot of hondas up there. I typed ls head and only came up with 4 cyl head parts, lol

Yes i do have to change springs and everything, i bought a whole cam kit from Texas Speed and used it on the motor for about 1000 miles before it started smoking due to a head gasket leaking so i decided to go throught the motor and do new rings and bearings while i was in there. So i will be using all my cam swap stuff in the new heads... Ya i check the sale adds on here and craigslist all the time for stuff and yes hondas are a big deal up here haha... Also thanks for the link

I was wondering the same thing, I have a set of 799's but have been afraid they needed a good port job before I put them on. Im on a limited budget so would a good valve job and milling the heads work for now? Don't forget the ls2 gto's also, thats what my heads came off of should be able to snag a set for 3-400 if not cheaper.

If you are on a budget I would get the 799s but before doing a head swap I would definately do a cam swap. Youll get a LOT more HP and change the character of your car. Later on do the head swap.
ORRRRRR
get the 243s now install them and when you do your cam swap get a set of ported heads at that time and sell your 243s they will still be worth about 4-500. But if you want more power on a budget its nitrous... if you want it all the time its CAM. I would do cam/gears first. You can get heads to match the cam later. There are many proven cams out here that are doing like 40HP increases over stock. Plus no money wasted on heads you may end up swapping for ported ones. Youll have more power now and time to save for even MORE power later.
Shook

Did you not read his first post? He already has a tsp torquer v2 cam
op, imo if you on a budget have the 241's ported. You will gain more goin that route than throwing on a set of untouched 243's or 799's. Now if you can afford to have the 243's or 799's worked, go that route.

Thats why i was lean more in the direction of the 243/799, i can always pull them off later on if i want to do a port job or anything... Plus i dont wanna deal with the screwed up header bolt in the 241's. So the ls2 head are the samething right? if so i will keep and eye out for a good deal on the ls2's or the 799's... Yay!!! i get to pick up my block today haha

Its not just flow. Its a more efficient chamber. Look at the chamber design of the 241 vs the 243 and notice the quench area, the smaller size, extra volume around valves, and area around spark plug hole. The valves are shrouded ALOT in 241 heads, they are unshrouded in 243s, now granted some of that will get taken care of with the porting, BUT the ~0.5 bump in compression is worth alot IMO

Or ported 243s and have 310+cfm. Dropping money on 241s is not worth it. I would personally just swap the cam now and save for nice heads later. If at all get the 799s and have a shop like TEA port them later. Their package is $1320 for the ls6 stg 2 heads

I went with stock Ls6, g5x4 cam, bolt ons, ud pulley, yank ss4000 and I raised hell. Defintely worth it if your on a budget. Heads are not really that hard to take off. You could save your money and buy some Patiot Stage 2 Ls6 heads. They come with dual valve springs (.650) lift. Just some advice...

Ok a good port job on stock heads is around 1000, why wouldnt i just save a couple hundred more dollars and go with a new set of cnc 243's or 5.3's from texas speed, i am with everyone else why would i throw money into the 241's and not have any room to grow?
I think i would rather just throw a stock set of 243/799 heads on right now and later down the road have a port job done on them when i have more money saved up. In my eyes the only extra money i would be spending is the price of the head and i would have a better flowing head right?

a good port job on a stock 241's can be done for alot cheaper than a 1000.00 Shop around... Also the only reason its being mentioned is because you said your on a budget. Obviously the 243's have more potential, but cast 243's will not out perform a worked
241.
