1.3 head

[will699]

will a 1.3 head run okay on a 1.2 block ?

yes they are very similar if not identical, ever so slightly bigger ports and a different cam but will be fine :)

This is assuming its a 1.2 carb engine....

[will699]

nope is spi will that make a difference?

[mk1nova_rich]

Are you intending on retaining the SPi setup?

[will699]
