Stealth pinch wall thickness?

[Draginmopars]

Nice work Draginmopars can't wait to see numbers thanks for all the pics and documentation. 

 Thank You

Hey Dragginmopars, you're quite an inspiration! I don't have the nuggets to do my
own porting. My porter said he would go as high as he has to on the intake ports;
I'll add a little weld across the top if I have to. The pushrod pinch is the real problem
area with BB mopar heads. I'll post some pictures when he's finished with them. I
left a Maxwedge head with him for reference. He said he could do better than that!

 Thank You, Sir You have an interesting project there

 The max Window is good at 3.650" and 1.380"+
I'm only going to be  2.475" and 1.250"+ or - .075"
I'm at the cross road
spool up to the line/Turbo, or
blow it off the line/ Pro Charger

Got back to the Intake side today
1 and 1/2 opened up
gotta chisel out some more,
at the roof

[ab7fh]

Is the valve guide removed? Or ground down? If it's ground down, I see that you left it intact on the intake side. Why is that? Just haven't got there, or something else?

[Draginmopars]

Thanks for looking

exhaust guide is ground down/
profile to the bowl curve

Intake / haven't got that far
removing the pinch/ opening the throat
is trickey
I do the guide work almost last
after the bowl work, then
measure/polish
THEN

[mopar_eric]

Very cool! Keep it comin!

[Draginmopars]

Very cool! Keep it comin!


 

NO more Work

 for a few days

My "Jaws" machine is broken
Gotta get it fixed first
 It pays the Bills, and to play

[Draginmopars]

waitin on seals and packing
at work

Got my hands, full of intake port.
wiggle room

gonna take the heads
across the street/machine shop
to open up the seat throat, to eliminate the step.
(seat insert to bowl area.)< +.010" dia.
Then
polish intakes.

One head Done

Looking Good,  Draginmopars
                                       It is very impressive what you have accomplished in such
a short time. What valves are you going to use? Thanks for keeping us posted.
                                                                              Cheers,  Budd

  1 down, 1 to go
will be using the SS valves
that came with head
 
there IS Still
 alot that can be done
would love to cut
this one in half, to inspect
if I could,
 find a replacement

 even using a Bore scope, and lights/small mirrors
 looking in the water side.
 can't see enough

I have a new set with flow numbers for sale if anyone is interested.

Is there a place to post FOR SALE ads on ?

Thank you.

 Maybe

how about some info
about those heads

 port window size
pinch area size
throat size/before bowl
 port volume

 FLOW #'s/ price   

[dusterdood]

He (Todd) was asking $899. Flyboy has started a site to post for sale items. You can see the thread stickied here at the top of the wanted section.

Mike I can not even get on the site because I don't post enough. But this has nothing to do with this post.Waiting for my machine shop to get busy on my heads. Sent them this post so they have a referance.Thanks Vic

[Draginmopars]

 puttin tha "Shine" 2 them

[ab7fh]

All done??

[512Stroker]

I'm lost... what did you do...  I have never ported/polished heads before.

[Draginmopars]

All done??

  I'm Never Done
 my elbow/arm is done porting for now
needs a break, So I have been
checking rod clearances.
 
Got the Triple springs in today
 mockin them up and checking clearance.
Crane R-284* .690"
then deck the block. Then,,
shave the heads for, Compression... Then
 

[ab7fh]

Dang, that's a big heap of shavings:D

I can relate with the arm/elbow thing. My wife just massaged my arm last night and I had to ice it down. I've been doing a bunch of grinding with a 4" in some awkward positions. It gets to be brutal after awhile.

[Draginmopars]

 I hear ya, even my air powered Spring compressor, acted weak..
 when putting the triple springs on
 to check for coil bind.
almost couldn't compress them
  @145 closed

Progress???  Inquiring minds want to know.

Also, how much $$$ is involved in getting the outside of the pushrod pinch area welded up?

The reason I ask, is that I just bought rockers for my stroker project:

-bill

[Draginmopars]

get the block tomorrow (decked)
then check
Piston to valve clearance again
maybe mill the heads some more

Can't say about Welding, Haven't welded, on mine.

[thecarfarmer]

Oops... I guess I gots to pay more attention to the name on the left side...  that's R5-P7 project's post.

So, is there a target chamber size after milling, or just as small as can be done w/ mechanical considerations (valve clearance, etc)?

Bump

Got the short block together 
1759g-bob weight
Cut .300" off the counter weights- to balance
Dang, Spiral locks, glad that's over with.
 next to check valve clearance to
 mill head. .075" + or - for compression
 

[R5-P7 project]

Looking good, how about some pics of those heads, if you're finished with them.  Thanks for the update.

Hello Budd,
How are You doing
on your project??

 My Heads are at the machine shop
being milled

Wait until you have to REMOVE the spiro locks! 

What kind of valve spring pressures do you have? Just wondering how long it will take until those crane rockers come through the valve covers.
