Hello everyone! I have a four barrel intake that has ECZ-9425-B written on it. Somebody gave it to me awhile ago, but I haven't been able to justify the cost of a new carburetor until recently. The truck is a 1964 f100 and my daily driver/only vehicle. I decided on an Edelbrock 500 and it just arrived in the mail. As far as I am aware, my motor is completely stock aside from the headers I put on it. I know that the intake CAN be put on the '64 heads, but I am wondering if it is a good idea. I have a good friend who works in a radiator repair shop and he is going to dip the intake in one of the acid tanks to remove all the rust so I can paint with engine enamel.

Should I just put the intake on the truck and not worry about it? Or should I look into possibly port and polishing the heads to better match the intake?
Are the '57 312 gaskets the same as a '64 292?
Is there anything I should know before attempting this swap?

I am also installing 3.25 gears in the rear end to replace the 3.89 I had, so it is obvious I am not looking for a huge amount of power. I was worried the new gearing would kill the very minimal power I already had. Previously my motor was running very rich so I am sure that was probably a main factor in my lack of power.
Thanks in advance!

As long as the heads are large port,then you should be ok to simply bolt the intake on.  Stock '64 heads will be large port.

'57 up gaskets will be the same.

Just bolt the intake on without concerning yourself with port matching or any additional head work.  The smaller primaries in the carburetor are expected to work well with the stock engine and the weighted secondary flaps are expected to minimize any low rpm bogs that might occur from hammering the throttle too early.
