172 inlet manifold

[Stopherson]

I keep seeing manifolds for sale on eBay that have been ported and polished to meet the gasket. Im going to be taking my manifold off any way to give it a clean. Would it be worth doing.

No waste of time trying to do it by hand as i doubt you will get the same size bore right through, best option is to buy some that have been matched via CNC

I agree CNC are better and doing it yourself is LONG! Lol
