Dan, have you made any "head way" on this?

I see where this is heading. Please don't lash out at my post.

I need to stop reading this stuff. Its got me thinking about getting another head to start playing around with. Besides the port and polishing I'm thinking about decking the head to get the compression ratio up o about 9.5:1. this should gain at least 2 hp minimum. My oldest brother runs a machine shop so the machine work to deck the head isn't a problem. He's a motor head too so won't take much to convince him to get it done for free. lol

Do it! With resources like that, what's stopping you?
|
Anyone want to donate a head for the sake of valuable research? Anyone? Anyone? Lol. Cheapest I have found is about $55 and not as easy to find as piston and cylinders.

If you do plan on buying a head, then make sure to measure the distance between the Head/Cylinder bolts. Supposedly there are minor variations in this pattern between some manufacturers of this engine, so not all of them will match up. I managed to do mine with calipers and the valve cover removed. Was a little annoying trying to get an accurate set of numbers, but doable.

Well, since my recent storage space into garage move, the notebook I write my numbers down on is buried or misplaced, so instead of measuring my current head, I would rather try to re-measure the stock head and post those numbers.
It's not too much work to pull the rocker assemblies anyway, so removing the fuel tank too will give me a much better view. |
I wonder if there is enough room to pull the head without removing the engine from the frame? I might wait till the weather turns to crap and just pull and port the stock head.
|
For the head only, there is likely just enough room if you can get the head bolts out.
Sorry I haven't gotten around to the bolt spacing yet. I wound up taking all day fixing my Jeep, and then ended up back at work all week. I am going to TRY and get around to it this coming weekend. |
