Team G big block intake manifold

can u measure the carb. pad heigth of it ? thinking I need a bigger plenum on my 505. standard port-right ? uncut?

Here are some pics to help you out. Don't know if was cut came with a project car I bought. Looks like a little blending done near the carb, ports themselves look in touched. I measured center of intake as there is a flat spot in the center.
