Anyone running L98 aluminum heads?
I am considering purchasing a set of these heads for a very good price, but am a little wary of the high compression that will be produced. Any experience with such. Maybe increase the chamber volume 6cc to 64 cc to lower the compression?

I'm running them on my engine. My computed compression ratio is 10.3:1. I use 92 octane on the street and 100 octane at the track. Check my mods list in my sig.
