As part of the rebuild I'll be cleaning up a B20F head. This will be used with possibly a mild cam Isky VV61, VV71 with advance key, or just a new factory grind (possibly also advanced). Want the torque curve on the lower end, don't care about 5500+ RPM. Its a city car.
Will be getting a three angle valve grind, considering 37mm exhaust valve.
Anyhow I would like some input as to what to address in porting Volvo heads. As I said I'm not building a fire-breathing 7000RPM racer but want to increase efficiency as much as I can without killing my low end response.
Anyone have experience with this?
Thanks.
Mario E.
