Guys,

I need to visit this thread more often....I apologize about that.

Im short on time now but will update you on the 245 shortly and a recent 225 head I did some work on with really nice results.

Give me a few days and I will get back here with that info....245 is days/weeks away at best.

-Tony

Hello, I just signed up today so I guess I'm a noob. Anyways I have been porting heads [many different kinds] for a while and I recently did my first set of LS1 heads for someone and paid to have an intake and ex runner flowed. They were 6.0L "317" truck heads here are some before numbers I found online of the exact casting... dumbass I am... should have flowed them before, the guy didn't seem all that interested in doing that, till they were done...

Casting Number 317, 035
Head: 2001+ LQ4 and LQ9 6.0 Liter Truck
Material: Aluminimum
Part Number:
12562317 -LQ4
12572317 -LQ9
12572035 -LQ9
Combustion Chamber Volume: 71.06cc
Compression Ratio: 10:1 LQ9 Flat top pistons
Compression Ratio: 9.6:1 LQ4 Dish piston
Intake Port Volume: 210cc

Stock Head Flow Numbers
Chamber 71.06cc----0.100---0.200---0.300---0.400---0.500---0.550---0.600
Intake 210cc----------66------142-----196-----228----236---238----240
Exhaust 75cc----------59------104-----137-----155----167---173----177

Here is after #s. Stock valves still etc.

I'm just wondering how I did.. you can't see from the angle of the pics, but I did make a hole where the rocker bolt boss was.. I made a plug for the hole and then blended it, and had him test it w/o the plug and with.. and the difference was NIL.... Thanks.

Default Heads and Cams

What would you recomend when it comes to brands of heads and cam packs? and is Trick Flow 500 HP GenX package a waste of money or a good investment?

Tony if I had a set of l92 heads for a 6l turbo setup could u port them for good numbers. I wana run edelbrock vr intake and carb. Would b blow through. Or is it cheaper and smarter to just buy a new set of afrs? I have afr 210s on my stock 350 block turbo setup running 8.80s at 153 with the out of the box race port not comp. And 8.4:1 w 15psi and t88 on pump e85 in a s10 that is 3600lb. Afrs flat make power.

Default exactly

It's like they're testing the first casts and then the commercialization alters numbers.. Nothing against anyone and I also forget the name but I've found heads that has similar numbers but cheaper than AFR

Default 317 heads

Does anyone have flow numbers for 317 heads ported by a professional? When I say professional here is the bar. My guy has a machine shop that is 3rd generation, been working heads since the 40's. Been porting them since the 70's.

I know the numbers will not be an exact match, just trying to get an idea without yanking the heads off.

TSP has flow #'s for their port jobs. Go to where they list their Cathedral Porting Service and there are flow #'s for both Stage 1 (stock valves) and Stage 2.5 (2.02 intakes)

Glad I could help! Yeah, I've always heard TSP does a good port/valve job, especially for the money.
