I am planning to use a set of heads that have the heat crossover in both center exhaust ports. I have heard they are crack pron, and recently have seen it on a pair of low mile heads. Is there an advantage to blocking one port of each pair of restricting both ports by some means? I have this thought of inserting a small tube in each port and pouring zinc or aluminum around it, or just pouring one of them shut. I do need carb het for wintertime driving. It was 19 degrees Saturday morning..
So much to do, so little time...
