Default L92 head questions.

Picked up a set of complete L92 heads for about 300 bucks. with les than 5K miles on em. I plan to use these on my n/a lq9 408.

I want to have them worked before putting em on the motor.

any recommendations on what i should have done? who is recommended to send them to fo a reasonable price

I realize they should probably be milled but to what cc?
spring recommendations for .700 lift?

more than likely will be contacting manley on a set of their race-flo valves

Kidding...I'm going to send my LS3 heads (which are almost the same) to AI. I believe they do LG's work too.

Am very happy with my WCCH Stage 2's from Richard...and he's one hell of a guy to deal with, even while I was deployed. Always got back to me as soon as he could and gave me a hell of a deal...
