I didn't CC the chambers, though I know I should have. I cut it back .250" on the first one, then made a template, and tried to match them. It passes fairly well by eye and feel in real life.

I...

Thanks. I really wanted to make everything "perfect" as far as smoothing it out and ensuring that everything was as close to the same as possible, but I thought I had better quit while I'm ahead.

OK, here are the results. I know there is definitely room for improvement, but I'm satisfied enough with my first attempt at porting a head. Thanks to all who contributed to the thread. I know that I...

Well, here we are all these years later, and I pulled the head back out and put it on the bench in the basement. I think it will go on my blue Omni. With some of the skills I've acquired since the...

That's much more than what I did on my practice head. I forget what the suggested measurements were, but I went on the low side of them. I want to say I laid the eyebrows back less than a 1/4" from...

That seems like it would be a good way to go. On my practice head, I used a compass.

Thanks again Todd. This has been an incredibly informative thread.

Thanks Todd. Do you make a template for the deshrouding and transfer it to the head, or do you measure and scribe lines with a compass or some such?

Thanks for the pic. I can seem some similarities for sure.

That's great. I can't imagine doing all of this with a dremel. I am hoping my mandrels come in sooner than later.

Thanks. I'm going to deshroud opposite the spark plug side, as I've read quite a bit of description of the measurements involved. I've seen a ton of heads which leave the spark plug area fairly...

Good for you. I'm waiting on some new cartridge roll mandrels to finish off mine. I'll post up some pics when I'm done to see whether or not I should bother with buying valves, etc. So far, I think...

Speaking of cams, it seems like I should decide on a cam before deciding on springs. I would like a jack of all trades, master of none type of cam. I like to autocross, hit the drag strip on...

I've been at it again while cooped up in the house due to this virus. I'm trying to take it pretty easy on my first head while doing something I think will hopefully flow really well. This is my...

1/4" from the edge of the stock valve when level to the face of the head, or 1/4" back from the stock curve at the face of the head?



That's a good idea. I could make a couple of key...

This is what I have. I guess I could make lines on it and measure that at the port? I just fear my whole process on this is off.
...

Alright. I'm on head #2 now. With this one, I'm trying to keep my process the same from port to port. I've deshrouded the valves and clearly need a better way to mark that. I think I need to put a...

Thanks Todd.

These cross buff things are pretty amazing. I did a few hours worth of work tonight and was able to experiment with another intake runner. I have the roof pretty high, and I stayed much narrower...

Thanks for the links. I'm having better luck on ebay than elsewhere.

Where is everyone getting their cross buffs? I see prices all over the place for these things.

Thanks. I'm actually pretty excited to see what it will look like with the ports cleaned up. I was just hogging out a lot of metal today to see what would happen.

I made some more progress today. I've decided to make this set of runners pretty large. On the intake side they are 1.5" or better where the guide is so far as I can tell. I'm about .04" larger than...

Thanks for the tip. I'll certainly try that one.

OK, I've ordered up a burette, but I'll probably just use the ones at work anyway...

Here are some more pictures. I did a tad more porting in the intake today. I have a lot of contour work to go...
