225 slant 6 intake/header

You can always get a set of Dutra Duals. They’re like $800 a set but they’re good and they’re the only thing I know of off the shelf that fits the Weber Side draft carbs if you really wanna beef up your slant. There’s an Australian guy that got almost 300hp out of his with those headers and carbs. But he also put lighter con rods and aluminum rockers and shaft (those are like $1,400 a set). And he put a bigger cam in too. Expensive build for sure. But I’m planning on cloning it myself
