Technical Early Hemi #2 (354 Hemi build thread)

I can give them a quick shave to flatten them out while I’m waiting for valve guides

 

Back when we could buy chunky gas!
Most surface cutters/grinders will leave a good surface for gaskets, but if you want to go the extra mile, select the head gaskets first and find out what surface finish they prefer.
Example
https://www.jegs.com/i/Cometic-Gaskets/245/C5211-045/10002/-1
"A surface finish of 50 RA (roughness average) or finer is recommended for proper gasket seal"

 

Haha! Basically I finish everything cast iron to one finish. Hasn’t caused me a problem yet but you’re not wrong. I’m picking away at this thing as I can afford it. The crank should be done soon. The bearings are on the way, I’m going to make a call tomorrow to get the guides and exhaust valves coming. This way the heads will be done. I can then move on to the block, I can deck it and hopefully pistons will be soon to do the boring and honing.

 

If you were close, I could CNC machine those heads to erase that damage.

Unless it were a 354. In which case I just have a stack of good heads.

 

It is a 354, I’ll just knock down any sharp spots. Not overly concerned about that.

 

I think you need another 857 Fargo with 354 Hemi it’s in Ft Sask

 

Oh my!!!! Tell me much, much more!!

 

I’ve owned for awhile, thought I would get at it , it’s complete in a storage yard. I race Bville with a 354 and thought I could use another. Don’t know condition of motor , never got that far.

 

I sent ya a PM, the red envelope on the top
right, I’m definable interested in it, even just the truck minus motor. Of course with is cooler yet!

 

cast iron boat anchor, i mean a cast iron boat/marine intake

 

Eek!! I would run one!

 

I know you would

 

edmunds 2x2 on my red ram

 

Me too!

 

Well these heads are determined to fight me, all was going well, until it wasn’t.
Got the first head set up in the surfacer, took 0.003” off and it cleaned up nicely, decided to take one more cut and at the very end of the head the table moved and a cutter caught the head and made a decent mess. I think it would probably be ok but I didn’t bother to take any pictures of it as I left in disgust with myself. Also broke two cutters so need to replace those as well. Not a good day.

The table on the surfacer just rides on rollers, I think I moved it to far to the one side and it kicked the end up. Rookie mistake

 

We've ALL been there...
Time for a good stiff cocktail

 

I did call Hot Heads and order some parts though!

 

Awww man, that sucks. Some days are diamonds........... and some not so much.

 

Yeah, it’s the very end of the gasket surface, I think it would probably be ok anyways. I may have a line on another set of heads, @hemiracer is checking into some, and I know a guy in Edmonton may have some.

 

What you really need for induction on your early Hemi. Would wake up the whole Peace country with this set up.

 

I do love multiple carbs!

 

Yesterdays whoops. I think there is probably enough there to still seal fine…

 

Sometimes i really wonder about my intelligence….thats a head bolt hole its fine.

 

Can’t like that.

 

Oh like away, I was too mad yesterday to look, the chunk missing at the end is by a head bolt hole. It will be perfectly fine, once I replace all the cutters on our surfacer I’ll skim a thou or two off to get rid of the other scratches.

 

The truck 2 x 1 intake with weird carbs would be pretty cool, cleaned up:
It would also fit (cover) the tall water ports in the head.

 

Yours?

 

Om thehemi.com a guy started putting two 2GC carbs on one of those using 1 to 2 bl adaptors, his wife got sick & never posted if he ever finished the project.

 

JB weld, not JB Quick.

Fill up the grooves, and the shave it flat with a utility knife blade.

It will seal just fine. No need to cut it more.

 

Oh yeah it would be fine, they look worse in the picture than they are. I bet 0.001” cleans it up. Just pisses me off.
