I just got a set of ls6 heads for 455 bucks. The need to be cleaned and resurfaced. Will getting the three angel valve job and having them ported be worth it? I was quoted around 500 and that's with a Polish as well.

wow, that is a lot of money. ebay all day long for 300 bucks for 243/799 heads. I hope that they have the 02+ z06 valves in them. advanced induction will clean, mill, and do the valve job.

i havent seen a set of 243 z06 heads on ebay for $300 in a long time. i think the current market price is between $400-$500 shipped.

Guy just sold a set in the classified section for $500.00 plus $40.00 for shipping.

How big of a hp/tq differece are the sodium/hallowed valves?

joecar

The hollow/sodium valves are lighter which promotes valvetrain stability which allows you the option of spinning the motor higher...

so they do not directly contribute to HP, but their indirect contribution to HP is by allowing to spin higher ( HP = TQ x RPM / 5252 ).

$500 for a port/polish and valve job is on the low side I think, makes me question the work but if they use a flow bench and can back up the work, it's a great deal.

It won't be worth it if you're running the stock cam with an LS1 intake. But if you're rocking a FAST 102 with something like a TRex cam, a port job is definitely worth it. Those are just examples, but like most everything else, it depends on the setup.

I say go for it - it's a nice step up from 241's but I would personally do supporting mods first and then throw these on.

You don't have to run a ******* Donkey Dick of a cam in order to gain the benefits of a set of properly ported 243 heads. There are countless posts of people putting down great numbers with ported 243 heads, baby cam and a stock LS6 intake.

Reading comprehension FTW boss.

243s flow marginally better at stock cam lift. You have to run a cam with higher lift and an intake that flows decent to get the benefits.

The 243 flows a lot better 241. I've seen cases where just swapping stock 243 heads alone was good for 20 hp.

There better than 241s of course, but nothing amazing below .500, which is where the stock cam is. The point I was making is that theres no way to know if getting his heads ported is worth it unless we know what hes working with. Ported 243s really shine above .500 lift. If he's on the stock cam, he's not going to take full advantage of the $500 port job. And if he has an LS1 intake he's going to see even less benifits. Not saying it wont help, just might not be worth it unless he has a cam and intake that can use the extra flow.

before i put them on im getting my cam and all my parts together so i change everything at one. im goin to make sure i have all the right parts matched together before i go pieceing together the motor. befoer i put them on i'm goin to get a 3200 stall and 3.73 gears( or find a stock m6 rear end for a swap. my car does have the ls6 intake on it. ported tb and a fast 98mm lid is otw. anything yall think im missing?

455 isnt so bad, I paid 425 for a low miled set that was just cleaned and resurfaced....sold the springs of them for 60 so when is all said and done I got them for under 400 bucks

If the budget is tight, you could probably skip the gears or put them off until last. I would suggest at least a 3600 rpm stall. Especially with a cam, the 3200 is probably going to be too tight. Not sure what power band you'll have, but the general rule of thumb is to get a TC that stalls 500 rpm shy of peak torque.

i figuerd when i did the stall i would do gears at the same time..

garygnu

do a valve seat leak check test .$500 is a great price for the head work you listed.dose it include a before and after flow bench ?

the hard part in all this is what to get next
..head's i got..but choosing what to spend money on next is the hard part...i've been told by a buddy of mine gears and stall is the way i should go..
