5.3L heads cleaned up flow chart
5.3L heads cleaned up flow chart hey was just wanted to post a flow chart of the PRC stage 2.5 5.3L heads im putting on my build
500 bucks in porting and this is what i got. I am happy with exhaust porting but intake side seems to me there is more left to be desired
and it has taken a lot longer to get it put back together then i thought it would cuz relucter wheel on new crank wasn't pressed on all the way and happened days before sema so it tooks weeks to get it sent back and new one finally got here today...but that aside...i think that the numbers before the porting were sadly low for what they are suppose to be. what do you guys think?

Verdad Gallardo well he was reccomended to me from a friend, but was told he does a good job. There was improvement in the flow but the base numbers were low before they were even touched that's what gets me. I don't really know what to think about the situation now.
Most flow benches should return similar but not exactly the same numbers. How recently has it been calibrated? Are the numbers factored for humidity and elevation? etc. There are variables there.
I would'nt complain too much if it were me ,,,,,,,You're intake #'s may be a little lower than those texas speed #'s , but the exhaust #'s are considerably higher . Good luck
