Very cool using common tools as a guide. Great ingenuity.
The man with the biggest screwdriver wins!!! :cheers: :cheers: :cheers:
And let me add a "That's what she said"... :glasses7:
LOL!
That is a good trick... :toothy1:

Also, to those that are wondering why on the intake side of the port entrance, why I suggested just a straight file between the two intake ports to smooth the casting at the entrance and recommended not thinning down that wall is simple. I like a good surface to be sure of no gasket leaks.
...i have seen some stock heads with really not much between those intake ports.I wonder how much it would matter if there was some leaking there.Wouldn't the majority still be coming from it's own port?
finished my porting..... about 9 hours. Took some time to try to get them as equal as I could. I'll post pictures when I get them all cleaned up.
The bill so far is:
60.00 - intake
23.00 - porting
P.S. - MrJLR, lol...... like the enthusiasm! :cheers:
Might not hurt to post the diameters of the sockets and the screw driver handle... I know the sockets are standard sizes, but that can vary depending on who manufactured the socket etc.... Interested to see how she turns out, these little guys are really handy for final polishing on the old dremel.
O.D. on the sockets
The size of the sockets depends on size of the valve. General standards for a good flowing port, you want an opening just above the valve equal to ~85-88% of valve size.

Guys,
RRR hit it on the head (no pun intended) when he used the word "Guide". The socket and screwdriver are there for you to measure progress (it does get exciting), and as a reference from one port to the other. I almost always have to go back and touch up a port or two when I think I'm done. This is where the reference is important. I've even used a small socket and passed it through the ports instead of the screwdriver. But the screwdriver helps with "straight through design" on the exhaust (and exhaust only), plus the handle works to size the port as well.
so? what exactly is your $ limit for a 'hopped up' 318.
please read the 1st two post of this thread, the money and the target (goal) is all in the 1st two post
