edelbrock intake help???

[wheels67]

Hey guys i installed an edelbrock performer intake on my 350. I forgot to notice if the intake had the center port water jackets in the middle....or if they were blocked off.......(big dummy)lol

I installed the gaskets with open port option...(didnt use the metal block tabs) Now instead of tearing my manifold and carb off to check, im hoping you guys have one laying arond to see if there is a casting port for the water jacket or if its blocked off.......

Mine is a dual plane #2101 461428casting...... HELP!!!
