318 head porting for the average joe

Thanx Bakerlite!

Those fingers have got me spooked lol.

Too much 'in-house' bickering on cylinder head mods these days?
Us wannabee head porters, like as much info as possible please!

Not all of 'want to' or have the inclination to buy aftermarket aluminums...
Head porting is an ART FORM and should be respected by all who partake of it...

Rusty 'J' heads are my favourite.
Grind till you make a hole and start again on another one...DOH!
