True, and when mine are done in freakin 09 (im still paying off) i will send ya my results,, my point beign that the 241's are already paid for. Not all folks are hammer down at all times to see that much lift, that much of the time. Depends on what he or she is doing with the car.

I'd be interested to see what your results are when you get them done
by me?, no
By Chris Ednres, in his book Chevy LS1/LS6 Performance, Page 70,,,,yes, He worked with Agostino Racing Engines in toronto doing airflow testing with different heads / intakes. ,,,in reference to my statement,,both heads ported and used with an LS6 intake,,the 241's flowed more until .400

I have a spare set of 853's i just disassembled. Aside from one guide needing replacement. How much would a straight p&p be? Doesn't have to be an exchange cuz they are 853's, i wouldn't expect you to give up a set of 243's.
I also have a set 241's on the car that i would be doing the same thing to. Once i get the 853's on.
I can send valves, springs, etc. if you would be willing to do the valve job/assembly as well.
You can PM if you would rather not quote specific prices on the open net

Most of the bigger shops design a cnc port use it for every head they port and don't flow any of them before they ship out. Except the first set they used to get the design done.
I have seen big differences in flow numbers do to the fact that the castings are thicker in some places and thinner in others. We port your heads for your car, most of the time we are designing a cam as well and it's all done with your combination in mind.
I can't put out as many heads but I feel our heads are the best going.
Thanks,
Harold
In this publication, they also state that a stock 243 casting flows 278. Which we all know is no where close to correct.
you mentioned that the stock LS6 head (no intake) does not flow 278,,,what is a realistic number?
Thanx again!
