Every time I've put 360 heads on a 318, I've gained performance. I usually cut them about .040. No, I haven't cut the intake side of the head and I've not had a leak to this point. So far, I've always run them on stock short blocks. I've usually home ported them.
- In the future I'll be building another LA 318 roller block. I have a good set of 360 heads and a set of Magnum heads I could use to replace the 302 heads that are currently on the engine. This build will see some short block work.
- What do you think, Magnum heads or 360 heads (1.88/1.60) for best performance?
