MaRu,

36mm venturies are an excellent choice on engines with S heads, however your T heads (32mm) will not come close to utilizing their airflow capacity and in fact, will again, reduce throttle response below 4000 RPM.

I'd suggest 32 or 34mm venturies along with a cam change as previously recommended unless you either install S heads or have your current ones CNC'ed to S specification (this is something we do).

Remember,...... ALL of the engine components must match and work together to get the performance you expect.
