Inliners International Forums General Discussion Engines GM 4 cylinders 151 153 181

Here is a link to a lengthy GM 4 cylinder thread on the H.A.M.B. . All of the information is not 100% correct , like here , but there is some good stuff. There's also an Ansen head if the guy still has it.
Checking out the 153 I see that it has no harmonic balancer just a hub and pulley. It seems a balancer would help but which one? 230? SBC? For the 5 port head it looks like a V8 header is pretty close. At least less welding than building one from scratch. And there are a lot of them laying around.
