LS L92 Heads

[sbctols1]

Thought I would share some info about the L92 heads. I bought a set of these heads for $195 a piece bare. These are factory GM cylinder heads. After I bought the valves and all related parts I only have about $800 into them, even with good springs. They have 260cc intake runners and flow 330cfm @.600 lift out of the box in rough casting. These came on the newer chevy pickup 6.0 liter engines, 2007ish. These heads have a massive intake valve @ 2.160". These heads will only fit on a 4.00" or larger bore. This is the best bang for the buck head you can buy. And they are a "stock" cylinder head. They will outflow most cnc'd aftermarket heads.

dont waste your time if you plan on putting these on a 6.0 they are too big for and ont do any good. only go with these heads if your going big inch. perfect for a 402/408 build, a waste on a 364 build.

These heads made 550hp with only a cam in carcraft. A smallish cam for that matter. They would only lack velocity on a 6.0. But would flow like crazy in the upper rpm range.
