Is it worth spending $ to uprgrade my stock LS6 heads on forged D1SC 347 LS6?
Most know that when it comes to forced induction aftermarket LS series heads are not nearly as important as they are with N/A applications, and that stock LS6 heads make BIG POWER on boost (just look for my sig on bone stock LS6 motor in my 02 Z06).
I am having a forged 347 LS6 shortblock with 224/230, 114 +2, .581/.592 comp blower cam, and for now am planning to run my stock LS6 heads, and should make close to 700rwhp on 12 lbs of boost (and 700rwhp is my goal). Million dollar questions, is it worth the $1,200 to $1,800.00 + dollars to get some Patriot ported LS6 heads, Dart 225s, AFRs, Ported TEA heads to run on my new set-up or not.
I am thinking not on a street car that sees 98% of its life on streets/highway, but do want to have the most responsive set-up for performance on and off the boost and are aftermarket heads worth head for the same set-up I will run on my forged motor, D1SC Cent. Superhcarger kit from East Coast Supercharging!
If yes, what heads would work great and are a great value and I don't want LQ9 72cc heads, as I am looking to make more power with less boost, and am staying with a higher compression (tham most) between 10 to 10:5 t 1, which makes BIG POWER with a boost (as proven on my stock LS6 motor)!

Decided that you live only once and just order brand new TEA Stage II LS6 heads that flow over 320 cfm at .650 lift and over 300cfm at only 5500rpm, for my brand new forged LS6 347 forged blower motor. Heck its only money and I am STOKED!
I can also now sell my strong running existig LS6 stock Longblock with 918 springs as a complete longblock when forged motor goes in this winter!

Actually it's better to spend money on heads that have a thicker deck compared to better flowing heads because you can just up the boost... The problem with boost and heads is that they start to raise because of pressure in the combustion chamber... Just go with the LSX block and a 6 bolt head.. =) Then no problem of pushing water... Seriously think about a AFR or ETP head (4 bolt)...Anything else would be money waisted in my opinion...

I can't even hookup now on the street with 600rwhp in the first 3 gears, and with my Z06 being primarily a street/highway driven machine, with occassional road racing and drag racing once a year, 700rwhp is MORE THAN enough power for me.

GUYS, trust me when i tell you that the EXPERTS at East Coast Supercharging, the premier corvette supercharging tuners in the Country, are running 14 lbs of boost on LS6 heads with their NOVI 2000 blower, on forged 346 LS6 motors, making well over 750rwhp (without any lifting issues at those levels).
