It really depends on what degree the job was done to. You can get it done from a mild p&p job to full head work. Don't expect outrageous hp gains, the 2zz head already flows exceptionally well.

Port and polish was far more effective back in the days of cast iron heads.

I think it was because those cast iron heads were so restrictive and because there were 8 cyls.

boring out your cylinders will require you to get bigger pistons, since it increases your displacement. i don't think it is advisable for the 'zz' engines since the cylinder walls are already pretty thin and close together.

the distance in between cylinders of the 2zz is only 5 mm.
