I purchased these heads for my '98 LS1 but I figured out they weren't going to be optimum for my low RPM build, so I'm selling them so I can buy something else. I had a machine shop check them over and they're ready to be built with your choice of valves and springs. The valve sizes are 2.08/1.60, chambers are 68CC but can easily be milled to a smaller size for more compression. Patriot quoted me $400 to have the heads refurbished with all new valves, a competition valve job, and having the heads milled to spec. So for $750, you can have a great performing set of heads that would normally set you back $1300 or more! I am open to trades of a 220 to 228 duration cam with a 110-112 LSA plus some cash or a straight up trade for an LS6 intake. If you're interested, PM me!

 

Low RPM build??

 

Yeah, I want to build a torquey engine for street use, under 6300 RPM. Stock '98 rod bolts suck.

 

how many miles on the heads

 

I bought them used, I have no clue. It's kind of a moot point anyway, as they'll need a rebuild to be used anyway, so everything will be back to specs when completed.

 

Sale pending... get in line if it falls through.

 

Sold!
