Cylinder Head Choice

ok, do you have any intentions of changing the gears or converter?? The 318 isn't going to get a lot of help with those gears and converter. IF you aren't changing them, then your cam and intake will be fine. I would then work with the 318 heads.
I would like to at least upgrade the converter but I don’t know where to start. What would you suggest I get to replace the stock one?

If I can’t work with the stock 318 heads I’ve got, what would be a good alternative to porting?

Thank you so much for working with me. Im fairly young, I live in a city where I don’t know anyone who understands cars and I’m new to working on cars myself - but I’m trying to learn as best as I can.
