Default Which heads for a naturally aspirated 402 LS2?
I'm thinking ET Performance heads, but which ones would best compliment a 402 LS2? This will be a naturally aspirated drag racing setup. Thanks.

Default cylinder heads
if it will be a drag race application, I would recommend the 255 cc. I know it sounds big, but it would work well.

I'm putting 225s on my 347 per ET recommendation. It will be a 13:1 motor though.

On a 408 that's not going to see many street miles, I would go BIG. Go with LOTs of compression, lots of cam, lots of gear and lots of airflow with the heads and intake. Go BIG.
