I cut the  Log on my 200 to accept a Weber 32/36
200 Log Milling Cuttin11
200 Log Milling Cuttin12
I scribed on the end so I would know when to quit cutting. I came out pretty square and took about 15 min to dress it up to accept the adaptor plate.200 Log Milling 78_log10
T adaptor plate is 3/8" which is plenty to accept threads.

When drilling log for the adaptor plate bolts make sure you have enough underneath to get 5 turns of thread, I had to re-drill two of mine.

My hat's off to you Stanyon! We used a table mill to do my 250 head recently, I guess
the end effect is the same Laughing .

Please post the results of putting that 32/36 on, I just got mine and would like to hear what
others think.

Best,
George

Oh yeah, a Port Divider goes a long way for performance as does the Dual Ex Manifold!!

I used a 78 head, if you are using a 80 and later head you will have to use some filler on the milled off area.

Thanks for the post back.
I have a '69 and a '75, neither look like that.
Are U familiar with the 'small log', 'large log', 'hex log' nomenclature?
R the latter 2 one in the same? I understand the '77 plus to be desirable
but can't tell (have not seen more than 1 or 2) if the last run (4 - 7 yrs.) on these heads
has any variation in design (volume, shape, name). (humm, just re-read ur post - it seems the '80
plus was another change?).

Thanks, dude - keep up the good wrk, excellent choice in carb.
Any interested? They're on Pintos here in USA...

80-83 has the slightly larger volume "hex" shaped log, 69-79 large flat-ish log, 77-83(D7-E03) have larger intake valves and hardened exhaust seats.

Thanks Seth. Seems like there's 2 "looks" to them (69 - 80, and 80 - 83)? And 3 volume changes?

"...77-83(D7-E03) have larger intake valves and hardened exhaust seats."
Yes, over on ford6 I see the flow test chart to show the (again can't tell if they're 1 in the same) large log or hex log to have as near much cmf as the OZ head... Just can't find one here in the North East USA.

I've got an E0BE head and the log on it isn't hex shaped.

sorry Das Boot:
"can't locate address" came up as error msg so could not follow the link.
I have the '69 250 & seek info on what later FoMoCo valves (exhaust and intake) to search out as upgrade,
and what to mill-out to for installation.
The head is off.
Want to make a lill tq monster w/o cam change. Will use carter RBS as it has good cfm & is 'low rise'.

All the exhaust valves remained the same throughout the years, the intakes have changed from 1.680 to 1.750 which I think happened with the addition of the hardened valve seats (unleaded gas) and the introduction of the EGR system.  I have read over at the fordsix boards guys going up to 1.80 and beyond on the intake, but as far as part numbers, I have no idea.  I'm sure you could get the seats and valves for an 1980+ head and it would work out ok.

As far as torque, about the best thing I've done is add a recurved DSII distributor with a hot coil and a 4 wire GM module less the ballast resistor.  Bone stock with just that addition is a night and day difference in throttle response.  The whole conversion ran about $100.  It is by far and away the best bang for the buck addition you can do to these motors.  

If money is a factor, I would probably look into shaving the head while it's off instead of playing with the valves.  You may want to do it either way because of the added thickness of head gaskets vs. steel shim that came on them.  The best gasket I can find is a Fel-Pro 1024 which has a compressed thickness of .039 while the steel shim that came on them is .025.  Most off the shelf gaskets compress around .050.  That's a loss of .5 - 1.0 in compression just taking the head off a virgin engine and doing nothing other than putting it back on with a new head gasket.  You could mill off .020 for the added thickness of the gaskets and however more for more compression.  It's roughly a 2cc reduction in compression chamber volume per .010 of milling.  Incresing your compression and ignition system would make it like a completely different motor.

Intresting, you never know when it comes to FoMoCo, but most E0BE and on logs are what they call hex shaped. They don't have a wide flat top, but intead a narrow flat top with more tapered edges.

I hadn't seen that Felpro gasket before just the other one which is .05" compressed, great info! Thanks for sharing that.

Sethg, I told you wrong. The Fel-Pro 1024 is for the 240-300. For the small six you have the Victor 3910VC which has a compressed thickness of .042, the Fel-Pro 7916PT-1 is .050 and if you have deep pockets, SCE will make you a copper gasket for ~$120 at a variety of thicknesses starting from .025. My bad.

"...a 4 wire GM module less the ballast resistor..."
the HEI? I think it's called (already have the DSII etc in some boxes).
DB:
Can see a pic from the other side of that hex? Know what yrs it was (just '80 -'83?)?
Moderator 'Mike" (over on ford6) has flow charts for different heads & that one is highest, stock (in USA).
Lrg log, sm log & hex...wish I had yrs for them.

Ah, bummer. Felpro should make a gasket like that for small six's

Chris, the first letter and number are a date code. The letter is the decade, the number is the year for the revision. C=6 D=7 E=8

E0 = '80, D7 = '77, C9 = '69, ect.
