It is your time, do with it as you please. My $0.02, and that is all it is worth.  But with a stockish build, I always just by stockish rings and measure the gaps.  If filing is needed, then I file, but I would say that occurs less than 10% of the time.  I can't think of a single instance were the gap would have been considered too large out of the box. 

Hi

How much for a couple of the turkey pans/inspection covers?

Thanks,

Wade

* even with progressive linkage the non used carburetor still has idle circuits feeding additional fuel on top of the primary carburetor * so don't load it

Thanks to everybody for taking the time to message and respond to my question and offer me help, its much appreciated.
Doug I'm sorry I forgot to posted how the vehicle is being used. Yes it's a genuine 67 gt500 and will be mostly street driven /cruising with the occasional spirited driving shifting at 6000-6200rpm at the most when doing some spirited driving,but mainly normal driving and cruising.
The car would be lucky if it ever went to the drag strip twice in its life with me anyway.
So I'm guessing twin 600cfms it is and I will have to get in touch with drew at air fuel and spark and speak with him.
The camshaft is a custom hydraulic roller from Brent at lykins motorsports who very kindly helped me out with the camshaft along with a set of morel roller lifters and Brent's roller rockers at 1.76.1 ratio.
Thanks again everyone for your help and suggestions.
Kind regards

      As having had that 8V intake as mounted to engines on our dyno, this with observation of the EGT's mounted for each cylinder, I couldn't advise that your plan is a good idea.
