Would twin webbes make a difference to my motor power. At the moment i'm running a single webber a bigger cam in a total recond engine there a bit shaved of the block and off the head.
Also i'm thinking of doing some porting myself and have plenty of heads to practice on if any one has advice or can send a diagram of the best approach area depths anything it would be much appreciated thanks

best thing to do is match the inlet manifold to the head so i think that means opening up the ports a bit and get rid of the casting marks in the manifold/ports

Put your finger in the port, imagine your finger is the air, if it hits anything, it is a restriction, remove it. The other thing to keep in mind is that making air turn a corner is a restriction. So keep radius' large and smooth.
