Is it gonna be worth me doing it on my 172 CUP, its a late '03.
is it a big job on a phase 2 172 taking the bottom bit that fits to the head off? ive had the top inlet off and already bored it out but getting the bottom part off doesnt look as easy!

how you "bored it out"?
you should match them together boss
with a miller to a certian size.
so i will just do the bottom to the same size boss!
Check them with smurf poo afterwards captain
I think what he is getting at matey is just boring them out to a larger size isn't the best thing to do, you want to match all holes to the size of the holes in the gaskets, any bigger and the gaskets wont seal
i think im right in saying u dont just want to bore it out, u need to make sure that u keep swirl to prevent the air and fuel from separating. And if u start to bore it out a lot, then u will loose ur torque?
im not an expert lol, correct me if im wrong!

Its also more of getting the mani holes to the same size, making them bigger will help, but the majority of upper and lower mani's are different sizes, which will not help airflow
