Intake manifold question: 2 crossovers??
Hello,
I just pulled my edelbrock performer intake on my 400, in order to block my heat-riser crossover port, wich runs under the carburetor to the other middle of the head.
When pulled, i noticed that there are 2 rectangular ports that also have exhoust debris...
The run in front from head to head. It's the first port on the intake..
Is it possible/better/better not to block these ports also?
I don't have any EGR stuff, or thermactor things running, just plain intake with an Impco 425 LPG carb on it.
Any advice/info? (Tim, do you know this? Never read it anywhere so far?)
Thanks!

I don't know of any way to block it off, it was for the thermactor my intake just had a big plug in it. If you really want it gone you can find some early 2 barrel cleveland heads that don't have it, but I really don't think it hurts anything.
