Hi.
I am building cosworth yb engine i buyed some parts and other are ready:

Holset hy35w turbo with ar 63 turbine housing. (would be equivalent to garrett gt3076)
Ported head 25mm inlet and 24 exh.
Long 133.5,mm rods, custom forged pistons 91.5mm with valve pockets.
Reinz GrA HG with std. Bolts..
std std crank, acl bearings
New HP oil pump...
205 block bored
...
Haltech ecu....

My question is what is the best combination about camshafts.

I already have purchased Bd14 inlet cam. My doub is if bd14 and std exhaust cam will work fine?

A tuner advised me to use bd14 inlet and bd14 exhaust.
Other run bd16 inlet and bd14 exh.

which will be the best combination? To my big turbo and high CR engine.

I will not want more than 430bhp due to the fragility of the block 205, but i would like good power and low torque engine.

My engine will run 8.5 to 8.7 static CR .

Thanks
