I am looking at the 180cc cast lightning heads, they flow great down low and over 260cfm at .5/.6 lift on intake!!! my question is for everyone that owns them, how do you like the quality and the difference you saw with them? any defects you noticed or just good quality heads? thanks

 

Quality seemed good to me. I had bought the bare heads though and had a local speed shop assemble them and clean them up. The speed shop seemed pretty impressed with them.

As for difference it's hard for me to say I switched from worked L98 heads and the LT4 Hot cam to the Pro Actions, and a XR282 cam. So it's not really comparing apples to apples. I will say the car is a whole different animal now with this setup. The car used to fall flat on it's face over 4500 rpms. Now the car doesn't want to stop pulling. Had I not killed the T5 I'd have some times to post, but I'm waiting on a trans right now.
