They where off my 5.3. They have 2.02 Intake with 1.60 exhausts and dual springs. They are ported, the flow info is in that photobucket folder as well.

why not just use the stock head and do a mild port and polish you dont need all that for a N/A truck, plus your out all that money might as well get some UDPs while your at it. i just dont think its worth getting new heads thats all.

Jason, do you have flow numbers for the stage 1 head? I did not seem them listed but then again I may have missed them.

I guess a better question would be How do I determine which heads would be appropiate for a 5.3 build???

For instance, My self, I am looking to gain TQ and HP all across the board. I plan to run the XR265HRcam Part number 54-412-11 Which specs out at 1200rpm to 6000RPM 265int/271ex advertised duration@.050 212int 218ex .522int .529ex On a 114°LSA. I would never run any thing bigger then that and with gas prices I may go a little smaller. So I think I might be better off with a stage 1 package.

Would you have any input on this package???
