Ok I see what your saying about having to buy 2 manifolds if I change the head later on. But today i had a somebody offer me a set of what i can only assume are twin hitachis (he wasnt sure). would I get similiar performance out of these carbs to the dellortos? considering i could probably save $800-$1000 (the dellortos i have found from www.recarb.com.au are $1299) would i see $1000 worth out of the dellortos compared to the hitachis?

Ive just had my pistons, gasket and bearing set, and exedy heavy duty clutch turn up today so im getting pretty excited haha. just waiting on extractors and all the cooling system gear and ill be set.

If I decide to buy an A14/15 engine is everything interchangeable between the engines. I realise the pistons wont be, but the cam, headers and clutch?
