ls6 heads

[Pony_Eater]

I met this guy today who has a set of 243 heads and ls6 intake. I want to buy them from him but what am i going to need to do to them before installing them? are they a direct bolt on?

[UTVols98]

New head gaskets and head bolts. Plus, delete the EGR delete for the LS6 intake. I'd replace the lifters while your at it.

[blackSS01]

Can't forget, the lifter trays. They are about $8 each for LS2's which are stronger. And screw it and do push rods.

[UTVols98]

Those too. Screw it, just go ahead and swap a cam in there while your at it.

so head gasket, head bolts, and lifters and trays ? anything else?

[c5z28]

probably the oil pressure sensor unit. Most people break them when they swap manifolds.

For the basics, that's it.

Unfortunately this is true.

If you are careful though, you shouldn't have a problem.

I've removed and reinstalled my intake 3 times and I've never had a problem with the oil pressure sending unit.

if i decide not to replace the lifters what would be the consequence of that and do you think i should get them ported and polished? how much will this run me? One more thing im trying to reach 400 hp so with headers, lid, heads, ls6 intake, and exhaust will i be there?

Replacing the lifters will cost you 120 for the set and 8 for the lifter trays. Since the heads are off, just replace them anyways. They're extremely easy to replace. What your gonna risk is lifter collapse with higher mile motors or spinning one in the tray when you do a cam swap later on.

For the 400 rwhp mark, no. Not without a cam.

ok im thinking of a cam and heads, some firend said 1000 hell put some cams on it, i have no clue about what cams acording to him ill be heating at least 430hp


what you guys think will be the best combo


plus his putting in some 4.10s for 150?

[UTVols98]

You mean cam. The LS engines are a single cam pushrod. With heads and cam and depending on the other mods, yes that is attainable. What are the spec's on the cam and what are the other mods?

[victor111262]

Like i said i have no idea he said it was going to be a huge cam, i have no idea how cams work he was explaining it to me but i didnt really pay attention ill get more info 2morrow

Best way to explain it. That's how I learned what they do and how it's done.
