they are ridiculously expensive, i would try sourcing a second hand manifold. are you wanting to run 40s or bike carbs?? but it would also be worth considering changing the head for a 1.3 item with the cathedral shape ports as manifolds are more common for them

And for good reason too.You get what you pay for with stuff like that.

im not doubting the quality of their work, i think its top notch and you will struggle to find somewhere better for setting up DCOEs :) but its a lot of money to be throwing at a C14NZ where you are going to see minimal gains with carbs alone :thumb:

Why not whack a c14se head with round ports on. They use bigger valves and will maybe raise the compression ratio a tad someone else will probably no more on that. Twin 40 manifolds are available for the round port heads brand new.

Im pretty sure it will lower the compression ratio, and T40 manifolds are available new for every head type

put a 1.6 head on it and skim it with t40.
