Heads- 6.0 or ls6 Hey all....
Im trying to figure out which would be best for my setup...
Im going to have a flp headers... radix supercharger, and a mild cam for the radix..

compared to air flow, price?

6.0 if going Forced induction. Great mid lift flow #'s plus larger combustion chambers for lower N/A compression that will increase your engines life.
I have 6.0L Absolute Speed Heads.
Here are the flow #'s on the intake.
Intake (Radiused Inlet):
200 - 153
300 - 210
400 - 261
450 - 280
500 - 296
550 - 307
600 - 317

hey thanks...
so the verdict is 6.0...
What would they lower the comp ratio to??
How much boost would I be able to run??
now the next question
Where's the best place to get these....
Patriot racing?? since they port and polish and springs and such...??

I went with Absolute speed heads. Ill discuss with you over PM's if you wish why i made that decission. Cores from Absolute are 400.00 dollars. However you will have no problem selling your 5.3 heads for 200.00 - 250.00 to make up the difference. LS6 cores are 900.00 - 1000.00 and the compression would be way too high for the super charger with the stock bottom end. I would determine your cam shaft, have your head ported to match the lift characteristics of the Cam. Also your LSA will be very important with the blower. I believe you can get 9:5:1 - 10:1 compression out of 6.0L heads. Go into the forced induction forum and ask there. They will know for sure. Some heads are off the shelf. I prefer custom ordered but to some price and waiting period are a higher priority. Your going to hear people answer your question with Patriot, Absolute, TEA, MTI so on about what heads to get. Do a search on all of these, look at the price, look at the comments. I believe you will find a decission on those factors.
