Alan,

Curious where in Wisconsin you got a quote to do cast iron welding… I’ve been looking for a place to fix some iron stuff… also curious where your getting rods for tig welding. I’ve got an old kitchen oven wired in my shop now so I could try welding on some heads that I want to change the shape of and fix a couple holes if possible. So far I’ve only had limited success.
I first contacted Midwest Cylinder Head in Iowa only to find out they no longer did any cast iron welding. Here is a link to the place I talked to in Wisconsin.  Good luck! https://www.castmetalwelding.com/

Overhead cams are always measured at the valve.  In addition, the low rocker ratio generally demands a lot more duration to fill the cylinders.  I usually run anywhere from 12-15 degrees more on an FE SOHC head than I do with my wedge FE heads.

sounds like a couple of nice builds.i am planning on a similar deal,but a 482 with pond block and ford aluminum heads that i have.also have a st of dove heads,one has damaged intake port that we will repair.
what i have found on the net and this forum,sohc can take a lot more duration at .050 than wedge heads.also they like compression,so 11-1 is minumum for a good pump gas.theres some good sohc builds on this forum.as far as piston,i will use racetech which is down the street from me,and they have done some custom pistons for mw before with good results.also diamond or cp ,but prices on them is sky high.
have 2 sets of cams,both around .600 lift,and isky max blower cams and a set of lsm cams with 282 duration at .05.not looking for big hp,just a thumpen street strip power for my 64 fairlane.
with your extra stroke,you can run a smaller dome and keep compression up.

There’s gains to be had if you do some bowl blending, guide shaping, and short turn massaging. Also as Ross mentioned you gain some fresh material to land a good 3/4/5 angle valve job on. A word of caution, it’s really easy to do a bunch of grinding in this area of the FE head, and either not gain anything or potentially make the head worse. I’ve been farting around with iron FE heads and 385 series heads for 25 years and have gone backwards plenty. Just part of the game until you learn the shape each head likes and where not to grind lol. Good luck.

Would love to get some contact info for the guy in Hudson… I assume Kevin had his heads repaired at Midwest cylinder head in Iowa…. I’ve used them in the past but unfortunately they told me they are no longer doing the cast iron welding at their facility.. I think the guys that were good at the task there all retired. I’m hoping to find another good place to get that service done, I want to fiddle with brazing some floors up on some of my own heads that don’t have holes into water jackets but I’d like to leave the major iron head repairs to people way more experienced than myself. Thanks

All of the oil goes through the cooler but there is a spring loaded bypass for pressure that is too high (for whatever reason).

Hello
 On the super cobra jet there is a  oil cooler, the oil that goes from the pump thru filter and then too the engine. Do all the oil goes thru the cooler ore is there a little by pass in the filter adapter on the scj engine so a little slip stream of oil not goes thru the filter?

I have a prepare Dove 427 SOHC set of heads with Comp Cams with specs that were lost.  I had a machinist more talented than I, and he generated the following;
Dove 427 SOHC Heads
1.   Comp Cams  953-16
   Intake°   Exhaust°
.010   106   106
.050   121   120
.100   129   128
.150   135   134
.200   139   139
.250   143   144
.300   148   149
.350   153   156
.400   160   165

   Lift .613   Lift .560
Duration @ .050 cam 242      
1) I have 2 different top oiler marine blocks that are std bore, but will require an over bore. 
2) I have a 4 3/8" RPM crank and rods BBC journal
3) I have the tunnel wedge intake
4) I am looking at advice for piston manufacture recommendation, compression target range for performance/hot street,pump gas.  I have access to non-ethanol premium at the pump (commercial account). 
5) I don't have a car, tranny, rear-end, etc.  I think it is kind of moot since I have the head assembled and spec'd already.
6) Where do detonation issues start to show-up builds discussed/performed/bench built?
7) Ferrera Valves 11/32" hollow stem F2024 2.280  Intake, F2023 1.900.  Chamber not CC'd (I was leaning on Members knowledge).  Plan is to take them  and get CC'd in my Community College class (personal enrichment course)

Recommend Pistons compression, manufacturer, special considerations, etc?

Thanks,
Gary

Side note;
I have Coon Heads with a different set of Comps Cams specs (for blower build w/ Monroe Intake Manifold Australia, 8-71), Crower Billet 4.25 w/o rods or pistons.  I will be looking for same advice in preparing this short block.

          Boy . . . . I gotta say as cool as all that gear-drive is (who's?  ???), it would seem like with all of that inertia of turning gears coupled with the hammering effect, that perhaps with a few good "throttle-snaps", or some brutal gear changes (with a tight clutch), and the camshaft gear retaining fastener & key would just maybe surrender?   :-\

          Looks like a good application for a "splined" juncture between the drive gear(s) and the nose of the camshaft stub.   :)

Herre is a picture of Milodon gear drive on a sohc. Not my build, but I know its possible.
