    Tools for cyl. head porting

    I've got the head off my 200 I-6, but am having a hard time finding the tools to port with. Have called all of the tool towns, as well as Harbor Freight with no luck. I found this on the Summit website but it looks like a bit more than I need - or is it typical?

    These appear to be some sort of grit like paper wrapped around the bit - I was thinking you'd be using some kind of grinding stone. Well, not stone but you know what I mean - like in dremel kits.

    Any suggestions where to look for the individual pieces, and what they are actually called would be appreciated. Thanks.

    What you need is a die grinder (either air or electric) and some cutting dies. Look at URLs below to get an idea. The metal cutting dies and what you would used to remove large bits and get the basic shape. Then you would switch to the paper rolls to smooth it out.

    Don't cut into a water jacket.

    Here is a nice set from Eastwood.

    They also have a porting kit.

    Thanks for the links, Patrick - this stuff is pricier than I expected.

    Kenny, if you see this, maybe you can pinpoint which shape of bits in this link you used on your head in the exhaust ports (I'm not working under the valves this time around) on your 200 head.

    I haven't even checked sears or other hardware stores for carbide tips - will do so this weekend. Thanks for the water jacket warning - I've been consulting the guys on the Ford Six performance forum about where and where not to grind.

    I have the "nose tree shape" but anything with that general shape would be good. If you're only doing the exhaust, one of these carbide bits and small kit would do. SAI-260012 is a bit cheaper from Summit.

    I would really consider taking out your valves and working the bowls a little. And at least lap the valves if you're not doing a valve job. I'm not convinced that only working the exhaust ports will do much but I'm not a expert on this.

    Thanks, Kenny - I'll ask about doing exhaust only on the FSP. Besides not having all the valve removal tools, I'm just short on time. Lapping - haven't heard that term before. Is that around the base of where the valve stem goes in?

    I have a spring compressor if you want to drop by this weekend.

    Lapping is a process of spinning the valve while pushing it against the seat with an abrasive compound. The tool is just a wooden handle with a suction cup on one end. It a good thing to do if you aren't going to have the seats and valves ground.
