If your sticking with stock heads, 3.23’s, it’ll be a little harder to achieve your goal. Ported 318 heads do very well except that’s an iron head that is hard to find a ported to do the labor intensive work and a rebuild. The aluminum head becomes more ch more attractive with lighter weight and better flow as cast.
The Speed Master/Pro Comp heads are a good match. With 20cc’s more to the TF heads, the very important velocity through the head may start to become an issue. “MAY” being the key word. I’m becomes build dependent from this point on. And it just isn’t the engine, it is the whole drive train. 3./3’s do not release the power as quickly as 4.10’s and up. For that gear ratio, a quick stop light to light tire burner is a not really going to happen.
The aluminum cylinder head at the 170cc area and a cam duration around 220 to 228 area would be very good.
Get a good torque converter and up the compression ratio on the engine and you’ll be pretty good
