The E7 topic was going a little off so I thought I would start a new thread here.

I am asking because I would like to perform a limited amount of portwork in order to acheive some improvement. I am not looking a for a max effort port job. Call my lazy. It would seam that the most gains would be working the throat. They just look restrictive.

Here are photos of the stock senior heads.







I am using this article as a guide so far.  http://www.popularhotrodding.com/enginemasters/articles/hardcore/0412em_porting_cylinder_heads/index.html

thanks in advance

Blended valve job and short turn is all thats needed. Sorry I have been busy and have not taken picutures of my embarrising rusty Dart heads. I can also clean them up for $500.00 including the valve job.

Those heads can do very well with the mods I mentioned. I need to take some photos of my heads so you know what needs to be done. I doubt you want to spend the money of shipping to have me do them.

The exhaust bowls are very thin on that one side on 1969-70 351W heads.  Be careful there.

Cheesy,

Can you post pics or dimensions on the port work done to the throat area of your heads?

I'll be home in a few hours and I will start by cleaning up the guides. I am not in a terrible hurry but the short block is waiting and I want to make a little progress every day.

im wanting to do the same a little every night then i would be done it what feels like no time.  my shortblock is almost ready to put together. needs to be decked and its ready. 


I'm just putting all the windsor Sr. stuff in one thread.

Here is some pictures of my Winsor Sr. heads. The first five pictures are how I got them. The next five are after i cleaned one cylinder up a little. Critique mine that way I know if I should continue on the other cylinders or just get a valve job and be done. It should also help him on what he needs to do to his heads.

Thanks
Colby

First two is how I got them. Next two is after i whittled on them.

My chamber is huge compared to yours. My chamber is 0.830 deep and almost 2.9 across from the edge of the intake seat. How do cc a chamber? Is there an easy cheap way? last pic is how i measured the depth of the chamber.

Bascially on the intake i didnt do much but even it out.

Bill let me have it. I want everyones opinion.

Good start. Don't need to mess with the guilde bosses, not enough gain to worry about.

That's what I get for skimming...   But, if you ever work on 351W heads, be careful of the exhaust bowl.

I didnt they were already done when I got them. Had no intentions of whittling on them more.
Good start any thing i can do different?

Lol thanks Scienceguy i figured i just didnt want anyone else reading to get confused. Shit happens thanks for looking. If anyone has pointers lay it on me.

We need pics of these rusty dart heads.

Thanks

Here is the work I started last night. I have one head disassembled. All 4 intakes are ported. I started 1 exhaust before it was time for bed. I read somewhere that the throat should be 90% of the valve size. I am not sure if that is at the valve seat or the overall valve diameter. I figured that the throat cut a machinist would perform would be 1.75 to 1.8ish in diameter. So I searched the garage for a socket and found one 1.75" in diameter. I rounded the throat until it would fit. checking the tight spots with a flashlight. I got all 4 intakes to take that socket about 3/8" into the bowl. I am a little concerned that a couple of them may have got cut close to the short side radius valve seat.



The exhaust I started  was going to get cut so that a 1.37" socket fits.

So, what have I screwed up so far?
