Default MAF - LS6 or 85mm

Hi Folks
I have a simple question, hopefully. I have the 90mm TB and Fast Manifold installed but runnning with the stock MAF (~75mm). Running with the large TB and intake, now the restriction is the MAF. If I change the MAF, which one should I use: GM 85mm (Part # 25418411) or 2002 LS6 (85mm - Part # 25341604)? I tried searching but not getting a clear answer.
Thanks
Bill

I wouldn't touch MAF unless MAF is faulty or you are putting down ~450 rwhp. Stock MAF is good for ~450 rwhp, so to me, it is just waste of money.

Hi
This is just a question - if I have 90mm TB and intake but only using a stock MAF(~75mm), doesn't that restrict the airflow going into the engine?
Thanks

i would go bigger, but only if u have hp tuners or something to tune it. honestly i would just do like waht im doing and run SD without the maf, i have a 88.9 mm pipe in place of my maf, i doubt its gonna get in the way lol. and the car has no issues in sd either
