Types of engine porting

[OLSKOOLROTAR]

Stumbled across this handy bit of info on porting . Not sure if this has been put up before so apologies if it has but I thought it would be a useful reference for anyone who was unsure or was wanting a port job in future.


Its a good read and its got pretty pictures aswell  :cool
