D series Cyl Head port and polish results?
What kind of extra BHP can be expected from boring out a D series honda Cyl head, anyone know? I have heard around the 15BHP mark but spose this depends how well its done and what engine etc.

yer sorry question was a bit bleak.... basically I shall be widening the ports prob 3mm extra all round not bothering too much with polishing. Has anyone got any Dyno figures from their mods and did they get it done professionally or homemade stylee?

that will KILL your power if you manage to pull it off without breaking through the water jacket
leave it to someone who knows what they are doing please
