what would be the difference in the power if i want to put 241 heads with ls6 (yellow) springs in a 5.3??????... the motor is stock but i already have some parts ready to install as well such as CAI LT's and a tune..

 

not worth the swap for 241 heads.

 

what would be good heads to swap for the stock ones?

 

take yours to the machine shop.
shave 0.20 or 0.30.
get a valve job and if you know how, break out the dremil and put a polish on the
ports.

 

The heads that are in my sig........
