l92 heads are casting numbers 5364 on truck motors. l92 or l76 heads are casting number 0823 on car motors. ls3 heads are 0821 on car motors. ls3 heads come with lighter hollow stem intake valves and sodium exhaust valves. you can mill them .030 or .035 to achieve 11:1 cr or better yet mill .015 and use cometic .040 gaskets which will help with quench and help prevent detonation and still achieve 11:1.

And is there anything that you recommend me doing to the heads before installing them as far as porting them and so fourth.

The castings are the same, it's the Valves...the car castings will have the lighter Valves as mentioned.

You can port them, they do flow alot tho.
