Why are the heads a “no-go”?

No way would I use a 318 head on that. I wouldn’t use a 318 head on a 318.

There is a fairly long thread on this very topic in this very forum.

Find another pair of heads. The 318 heads shouldn’t be an option.

they want as much to rebuild the 587 heads as it would cost me for a pair of speedmaster aluminum heads... $950 and thats with me supplying new valves, the correct springs, seals, locks and retainers
