I have a stihl 038 farmboss I'm converting to a magnum. I have some questions about porting the cylinder. Any specific specs to go by on the exhaust/intake ports? I don't wanna go to much. I'm new to the site and ive been reading alot in here and I got the base of the cylinder figured out as far as opening my holes up, removing a fin or grinding the bolt head a little. Just a little worried on the porting. Any advice will be great. Thanks guys.
