Hi!

The 305 TBI "Swirl Port" heads are the worst ever made

Since you are in Sweden I don't know how many junkyard Chevys you folks have access too. But if you can get a set of 305 heads from a TPI or carb powered 305, you can work with those. Just follow the instructions in the link at the bottom of my sig and you should come up with a set of heads that will definitely flow like Vortecs--but for hundreds of kronars less
