421 head selection
Ive got a LQ4 421 with 4.125 crank, its in a 02 2500HD. right now ive got the stock heads on it. Im looking for a new top end combo starting with the heads, and not sure what heads to go with. The goal is low end torque but i would like it to scream at WOT. I would appreciate any input yall have

On the budget end I would go with a set of massaged L92's with a L92 truck intake 90mm t-body..
If you have some coin to spend ..a set of Trickflows or AFR's with a FAST lsxrt 102mm intake with matching throttle body..
To make the most out of the combo , and get to your goals have Pat g. on LS1tech spec you a cam..Good luck!
