Hello all those wondering and waiting to see if I ever was going to finish Project Echo Seven.

Well for a refresher for those who have not read the prior threads here are the links to them.

Project Echo Seven http://www.foureyedpride.com/phpBB2/viewtopic.php?p=68484#68484

Project Echo Seven Part 2 http://www.foureyedpride.com/phpBB2/viewtopic.php?p=69924#69924

Ok after those who have never read these threads and those who have and reread them I am going on in this thread. I will try and get some more pics up in the next few days. If anyone replies to anything from the prior threads in this thread please make it easy on me and link, copy, quote whatever.

So, I have completed the exhaust ports and bowls. I had previously started working on the intake ports but the sad part was there was so much time inbetween what I had done and where I started again I needed to finish all the exhaust ports and start over on the intake ports.

If I don't hit water I intend to use these heads. This would be a good time to tell that I did cut into a pushrod tube. I should have known I was getting close but it was opening up so well.

Here is a tip that you might like to know incase you get close to a break through. Sometimes the carbides "jump" while grinding/cutting. This is normal. Near as I can figure it is basically when you go against the grain of the bit. Well I have yet to see the iron look as if it has a burn mark in it or a hot spot. If you see something like a hot spot in the metal and believe me it is obvious, then you are close to breaking through.

Anyway, IF you are porting your intakes AND you break through into the push rod tubes you have it big enough :roll: :? :lol: . Do not try this near the water jacket :!: Well the fix for this problem really isn't bad. I have 2 choices, epoxy, or choice 2, slide in 1/2" copper tubing and cut it off and seal it. I am planning on going that route.

PICS SOON.

Thanks Capri

There is a set on eBay now $900 fresh and ready to go, 54cc chambers less his triple roller cam springs.

OK, with all due respect to the web space available on this site I will post the URL http://www.velocity.net/~lauriekay/echo7a.html to the current updated page and link a few pics.

Now that I have snapped a few pics and edited them I will work to get some more pics and some more done in the next few weeks.

If the weather continues to be a bummer and keeps raining and or snowing the drag strip shut I will be working on the heads. Not to mention I have a set of GT40X headsnow to work with.

Why did you removed the valve guide boss on exhaust side? You definitely need that for valve and valve guide support .

Out of curiousity....

Is the guide shorter regarding 302 heads versus say... a 351C head?

The reason I ask "Old_Timer" Alot of porting guides I've seen in both the Performance Ford Engine building guide & sites on the internet recommend eliminating the exhaust guide "boss" all together versus forming it to a teardrop type shape.
I would think that you might give up a little durability(faster guide wear due to roughly 20% less surface area) & maybe a little worse heat transfer to the head through the valve itself...

I could be wrong & I do so love learning engineering principles....;)

Right this very moment I do not know the spec that I was given for total exhaust guide length I need. But I did measure it and found I had enough guide with the lower guides removed.

I'll find that spec and post it.

Well I finished up the Intake ports on the one heads. I will get some final pics of the that head VS the head that has one final stock intake port left.

Visually you can see the difference.

What I have left to do is finish all the intake ports...
finish trimming the intake guides
finish some bowl work
polish out the grind marks
repair the pushrod tubes

Then I will take the castings and have them pressure checked, then hot tanked, them milled .020" - .030" and install the 1.84" intakes and 1.54" exhausts.

Then bolt them on.

Interestingly enough "Ed" has refered to these as 100 horse heads. I highly doubt they will reach that kind of potential. I'd be happy with 40 - 50HP

OK So I didn't add the pics when I said I would. Like it is a surprize to anyone LOL here is the next site I put up and I hope to have another one up this week with the other things that were done.
