Hope you guys arent getting bored yet



I need someone with a 13b intake on the shelf to match it to the picture and let me know if the gaskets would be the same so I can just tell the guy at the parts store "13b"

And if anyone knows a site about making gaskets, what to use for what, temp stuff, etc. I would appreciate that too.



And anything about the intake rings would be great!. mine seem too big in dia.

Thanks a whole lot everyone, really.







PIC: note the top right bolt hole is off pattern from the other five.

it's similar but not quite the same, bolt pattern might match up, but the ports are different.
