ls6 .heads 243cc

has anyone done the LS6 head mod the 243cc . if so what did you need to run the mods and yes i know since going that far a good cam is another part that would be going in also .

I was reading about heads today. Injectors, water pump, intake and tune are things I read need to be done when swapping the heads.

Why would you bother...outside of a 64cc combustion chamber, compared to the stock 71-72cc combustion chamber, there is no difference. Everything is the same and all it's going to do is bump compression by a point or so (not a .1 but a full point). You'd be better off just swapping the cam and getting a tune and saving the cost of the LS6 heads and with the LS-series a cam swap doesn't require the heads to be removed.

Seems like a lot of cost and work for little gain and having to worry about getting a tank full of bad gas or riding on knock sensors all the time.

what about the l92 heads the same as the 6.2 heads i hear they make a big difference too but you have to change the intake manifold tho

i have too take the heads off anyways . i have the famous gm exhaust manifold bolt broken in my heads 2 on the left and on on the right and they are at the back so not really room to drill them out

That would make a whole lot more sense than LS6 heads...you will need a new intake and rocker arms for the new heads and you'd be better off getting a cam specifically for the rectangular port L92/LS3 heads.

If you're going to the trouble of a head and cam swap the L92s and a cam are the route I'd go.

I researched building everything up to a 427 stroker with the L92/LS3 heads and a Magnusson supercharger. Once I went with the new block, forged internals, stroker kit, heads, cam, headers and supercharger I was well on my way to the cost of a DMax conversion, which is the route I'll be going. Didn't make sense to spend a ton of money on a gas motor that was slower than and got worse gas mileage than a diesel. And diesels make it soooo easy to turn up the power.

well if i have to yank heads to get those bolts out i was thinking why not put better performing heads on . i just heard alot of ls6 because its direct bolt on but also heard the l92 and they make good power upgrade. now if i did that and cam i would for sure need bigger injectors and run like a kenny bell boost a pump , and a tune of course
