These will be off my truck very soon. Like next week soon. I have a set of 799 heads. They had 18000 on them when I bought them from another member on this site. I maybe put another 1500 on them. They have 918 springs on them that have 1500 miles on them. The cam is a comp cam Xfi 275hr 54-426-11 222/224 .566/.568 112 lsa cam has around 5000 miles on it. I'll take 450 shipped for the heads with springs and 225 shipped for the cam. Or if you want the whole thing I ll take 650 shipped for it all. Call or text me 405-740-7765.

I don't want to separate the heads and springs due to the fact I don't want to dissamble them. Am I lazy....I ll have to say a bit.

Sold!!!!!!!!!!!!!!!!!!

 

Not familiar with the 799 casting.. are these lsa heads? 5.3?

I recently stepped back into the world of ls as i took a break when i sold my camaro a few years ago in favor of a 550whp gn...

 

Yeah they are off an 5.3, alot of people use this head especially the 6.0 guys looking for added compression over the stock 317s that come on the 6.0l

 

799 heads with springs for $450 shipped? One hell of a deal. Someone should jump on this one quick. Early morning bump for ya

 

I got a 6.2 truck 2011 would thes heads work I have the turbo kit from a member off here as well a custom grind EPS cam

 

I'm not a 6.2 guy but Im thinking those a square port heads. These are cathedral type heads and I believe they will not work with the intake you have.

 

Hello,

I own a 99 Tahoe that I will be dropping in an 00 6.0 out of 00 2500HD P/U.
I know you stated that many are using these heads for added compression.
BUT
I will be adding a blower to the set-up. Will these heads and the blower make things worse.

My goal is 500-600 hp. Cam boost friendly?

thanks

jason

 

You have the iron 873 heads on a 2000 6.0 I belive. They have larger compression chambers then the 799 I belive 71 vs 63. The larger the combustion chamber I ve always been told was better for boost. So I think your better off with the 873. I would look for some 317s there the aluminum vs of the 873 and you can find them cheap on eBay. Like 230$ shipped on eBay right now lol

 

Gas,

799 is the same casting as 243s. They do not have the special valves though.

 

your honesty is awesome , your trying to give a killer deal on a set of 799's all while steering people in the right direction for thier combo , and for those who dont know these 799's are te truck version (solid stem valves vs hollow) of the 243 ls6's


JFOLM guess you type faster
