318 head porting for the average joe
Happy new Year to 318 head porters and other porters too lol.
I have no access to a flow bench as they are pretty rare beasties here.
I have built David Vizard home flow bench to ascertain 'valve opening' pressure drops.
I have a 1965 closed chamber head, which dropped a 1.88 valve so I've ported it out to 2.025 tulip valve.
It was cheaper than getting a new seat fitted doh...
By a strange coincidence the port chamber was greatly offset to allow easy fitting without shrouding, very like a 340 head,
Bowl blending isn't too bad either as the 318 port is rather small.
Will it be a head saver or a 'flat on its face' wrecked head???
Photo's to follow when my Android stops playing up DOH!
This is ken's 1.88 and the 2.025 goes right out to the exhaust valve like a 340 head does.
