Was looking through the new summit catalog, and noticed that there were some new lt1 heads out from trickflow. I didn't know that there were any aftermarket heads out for the lt1 other than exchange programs for porting stock ones, and the lt4 heads. Have any of you guys got opinions/experiences with them?

 

Big chambers. Can flow similar to a ported LT4 head with lots of work. Better for booster cars, will lose some compression on a stock setup.

 

I think AI is working over a set and should be posting some numbers in the near future sometime.
