I know the intake bolts are different but what else? I got heads sitting in my garage and my big brother told me they are LT4 heads I will try to take some pictures of them later they got angle spark plugs and I want to sell them to a friend of mine he wants LT4 heads but I want to make sure

 

Actually, it is the raised intake runners on the LT-4 heads that are the major difference. And you need an LT-4 intake to match the raised intake runners. You can check the casting numbers on the heads to make sure they are LT-4s.

I toke some pictures and there was a number 3183 I hope someone help me

 

It looks like you've got an issue with web-hosting your photos,

Upload them on www.imageshack.us or www.putfile.com so you don't run out of bandwidth..

 

You looked at the wrong number LT4 casting number is 10239902.

Also the runner is not raised really, it is TALLER, the floor is in the same spot and it is a lot bigger.

there was a smaller number size it wasnt clear I will try to clean that area and get the number so any chance they are LT4s from the pictures?

 

Reguardless of the casting number, those are LT1 heads not LT4's. You can tell by the lip of the valve cover rail.

Not only that but quite possibly the most dirty nasty looking heads Ive ever seen.

 

hahahahahhahahahha you wont believe how much they gonna pay for those dirty heads

 

You did read my last post correct... right. Those are NOT LT4 heads. I wouldnt pay more than $50 for them.

 

yeah I read your post correctley but ppl in my country buy LT1 heads for 150$

 

That alum LT1 heads regularly go for that or more on here if they are in good condition.

but man, looks like that set has taken some abuse

 

I already got a buyer for them thats why I want to make sure if they are LT1s or LT4s

 

If you sell those as LT4s, someone's gonna kick your ***.
If you represent those as anything other than rebuildable cores, you're also gonna have someone pissed at you. Those are BEAT... and need a complete rebuild to be worth anything. the springs and valves are both in BAD shape, and the valves are almost certainly siezed in the guides. it's also VERY likely that the valves will destroy the guides due to the amount of rust if a machine shop tried to disassemble the heads for cleaning and rebuilding.

Most folks here frown on ripping people off. I hope you reconsider selling those, or at least provide clear, close up pictures of the condition before you sell them. Certainly don't describe them as in any way ready to use. My machine shop would likely charge 800 bucks or so to make those ready to use... nearly what a set of ported performance LT1 heads would cost.

 

first of all I didnt put this topic to sell them to the fellow members I just wanted to know what those heads came from

second I already said I got a buyer and he asked me to look for LT4 heads for him and when I look at my garage I saw those heads and I told him they gonna cost u alot of $$ just to rebuild them as a stock heads and he agreed because he swaped LT1 short block into 90 altima and he want to finish the project as soon as possible I told him I dont know if they are LT4s or LT1s he told me just make sure what are they and call me ASAP but I think I was wrong when I was thinking of putting a topic here and ask you guys so Im sorry for any miss understanding I hope the admins delete this topic,Thank you.

 

i wonder what i could make full bolt on lt1 with lt4 heads/edelbrock intake
