600 CFM, all I need. Check my math!

So you drove over to Summit and got it, cool!
If you don't have to change jets, you can test several combinations in one outing. Takes seconds to change rods and springs once you get the hang of it.
Cross reference the different model's venturi, jets and rods, do a little math, and you will find you can do a lot more than the dots shown. I didn't have an AFR meter, but I had fun messing with mine.
Good luck!

I drove (not in the Scamp) and got it. The carb had a big thick gasket (I think it's a heat insulator) and about 4 regular gaskets. On the Edelbrock videos they only use the one gasket supplied. So tonight I removed the carb and all those gaskets. The nuts weren't even tight. I could have loosened them with my fingers. Then I cleaned off the top of the intake. I put on the brand new gasket in the Edelbrock box and put it back together.

I had to get a son to read the tiny number on the metering rods. I did a metering rod change only. It was late when I got done so I didn't even crank it. But I have a couple questions.

All those thin gaskets and insulator gasket stacked up must have totaled an inch thick. Was I wrong to remove the heat insulator / spacer gasket?
I moved the timing advance hose to the total advance (the lower port) and plugged the timed advance. I read that timed advance was for emissions car. Since the car has no emissions I figure I would be better off with the total advance. Am I correct on that?
This is probably a silly question, but I must get clarity. After I cleaned the top of the intake, I put the new gasket on. The new gasket fit the studs correctly but ... the left and right inner sides of the gasket bore closed off some of the opening of the intake. Or think of it like this. The intake square bore was larger than the gasket sqaure bore, on the left and right sides. I got nervous & took the carb back off and compared the new gasket to the 3 or 4 thin gaskets and heat insulator that I took off. They were all the same bore size. So I put it the new gasket and carb back on, and bolted it down. It must be OK I guess. Question: wouldn't it be better if the gasket bore and intake bore were the same size?

Once I did all that it was too late to crank it up. The wife doesn't like it as it is, so cranking it would have only created drama. I don't know what to expect from it except a PITA to crank from cold. And it's very likely to rain tomorrow, so I won't drive it to work. And after work I have a college planning meeting. So I may not get to touch it tomorrow.
