Well I found a set of used 862 heads around town on Craigslist, and I'm just wondering how well those heads perform? I'm doing a budget build right now and aiming for 450-470 RWHP threw a 6spd, with a MS3 cam, and 11-11.5:1 compression.

This is my 1st LS motor build so I'm just looking now, and there pretty cheap (75 bucks), so I'm thinking it's a great deal jump on it or there junk?

 

450/470 rwhp and cheap do not go together. unported look for 243 casting, ported that price is too good to be true.

 

thats what Im looking for also.243 ls6 casting off of a 05-06 gto.part#12564243.

 

I was still gonna have them ported and 2.0 valves put in them, do the LS6 casting flow better than a ported 5.3 casting?

 

Those heads are crap. Like said previously, go for the 243 casting.

 

So no one really answered my question.....

Are the 862's worth using on a small cam + N20 car?
