Intake matching and split

Recommended Posts

In my continual quest to keep messing with my head :cheers: I decided to match the intake and put a edge on the intake split. I really hadn't thought of these things until I really got to looking at the intake manifold and some research here on TT. Come to find out the rubber manifold responds just as well to sanding with my dremel and bit as the exhaust polishing and casting mark removal on the head. I had to be careful since it is softer than the aluminum. Still tough and wore down sandpaper quickly. 220 and 400 with a couple of spots using 150. When sanding it the black wore down to a yellowish surface. The intake has its own "casting marks" with a fairly raised ridge running along the upper and lower portion of the manifold. Besides that I felt with my finger for any kind of rough snags or steps up or down of material that didn't make for a smooth transition. Have to say that I am pleased with the result since I can tell a obvious difference from start to finish.

I first started by taking away material from the head that raised or stepped above the manifold. I simply took a extra fine point Sharpie and marked the material. Removed the manifold then grind down the part that had been marked.

Here is the finished job with the raised casting marks taken out which I did with the manifold off. With the manifold back in place I could reach with my finger and feel the lip or step down of the manifold to the head. I took out quite a bit of manifold material on the right and left. With it on the head I was able to grind and sand until there were no distinction of transition. The intake split took a good bit of filing but came out sharp.

Just to show how much a mess it made.

Manifold off to view other end.

One more thing for show and tell. Before I started the work I have done on the head I agonized for a while over how to take the valves off without paying someone. I found a large C-clamp that I hadn't used in years, cleaned off the rust and made a notch to allow the valve and keepers to extend out of the retainer. Presto, a old neglected clamp saved me some $ :moon:

Nice job on the C-clamp, I like it! :moon: Tip....replace the O-ring on the carb adapter, they have been known to leak air.
