What do ya'll think about getting a set of stock heads to get them ported/polished and maybe a little bigger valve. I would also be putting a new valvetrain on them. Are there any major pitfalls with the stock ls1 type heads?

Thanks for the help in advance.

 

none go for it. Make her sing in the higher rpms

 

I've got ls-6 heads on my truck (but I get GM employee discount) I would look at some of the CNC ported heads from one of the site sponsors, internal engine has a ton of posts on heads althought they seem to be very car (f-body) centric and don't reply well to truck based questions, Oh well at least they STILL build our trucks.
