header design with sequentially siamesed exhaust ports?
Only some of them had shared ports. I know for sure the ones used in the later lesser Imprezas did. From the shape of the manifold, the gasket surface is just a round hole like the BMC, not like the Olds at all. Cool, someone's heard of them. Is a head swap out of the question? I've...- renyo

header design with sequentially siamesed exhaust ports?
I was wondering about the impact about the odd heads on my engine on header design. I have a (Subaru) H4 - 16v (gasoline, spark ignition, naturally aspirated) engine. The exhaust ports on each head are siamesed together. The firing order however fires left front, back, then right front, back...- renyo
