Have read other posts for your problem. agree even iron blocks may not be flat. Always put in new head bolts because old ones stretch from high torque and heat. Make sure bolt holes are clean and dry. Excessive water or oil in bolt hole will cause hydrostatic lock which could give false torque , and sometimes may even crack block. Liner height on an engine should be within specs. Gasket sealer should not be necessary. May cause sealer in gasket to seal improperly.
Correct overhauls raise temp slowly till operating temp. Run at med range rpms for about an hour at that temp. Then always retorque head bolts again.
Hope this may give you a direction you haven't tried.
Best Rich

1)Check your liner protrusions, they should be .025 above the block deck.

2)Head bow can not exceed .006 the long way or .003 the short.

3)Check alignment stud holes for depth ..a planed head may have reduced available clearance for guide studs and /or debris in holes keeping head from seating properly.

Towards the last of the 4.107 series production run they where fitted with Dry liners as fitted in the 4.108 series ,the early wet liners have the habit laying flat with the block face due the bottom seal rings crumberling to age ,heat ect,if your engine has a row of 4- 0.125 holes along block on hp fuel pump side then wet liners are fitted.The liner flanges should protrude about 3 ot 4 thou obove block face this allows for crush on the btm seals also to help with head sealing. CHeck that you have been given the correct gasket not 4.99 series joint these are 0.125 bore size smaller otherwise the same if wrong the fire ring burns out. Head tensions early 4.107 7/16'' studs 42 ft lbs later series 1/2'' studs 60 ftlbs, to check surfaces ask for a small amount of bearing blue at a machine shop this will help show any high/low spots.DO NOT use any monkey spunk on gasket surfice this causes the joint 'walk' during tensioning.Good luck.

EIther something is warped (block or head) or "Ran a tap and die on all head studs and nuts torque it to 46 foot pounds+." the reassembly isn't right. Sometimes the maker will expressly tell you that the studs cannot be reused, they must be replaced. And the torque sequence is just as critical as the correct torque.

Find the factory procedure for the engine, see what has been omitted or done differently, and the answer will pop just like the new head gasket did.

If your 4.107 is fitted with the end of series 1/2'' studs then these are to be torqued to 60ftlb not std 42ftlb the last of the 4.107s had dry liners as in the 4.108 early 4.107s are wet protrusion has to 3 to 4 thou. some manuals say head is not to be machined --never had problem taking to 15 thou checking valve face clearance. Check correct head gasket some supply 4.99 joint dia 0.125 smaller than 4.107 this causes fire ring to burn out. Put joint on DRY otherwise joint will walk during tensioning process.

If head &deck have corrosion marks use a high density silver on both surfaces leave fo 4-5 days before lighting fire,this method also used when you have to re- use gasket for what ever reason.

Had this on a 6cyl. Check the block does not need decking,heads are not the only thing that warps. Check the liner heights as well. If the head is OK, you can bet it will be one of these or a cracked block. A cracked block can be tested most times with the 4 part spray cans you buy in a crack test kit.

If your 107 is late model last of the production run it will have 1/2'' head studs these are tensioned to 60 ft lbs they also have dry liners protrusion should be 0.023/0.027''. 107 wet liner protruion =3-4 thou. Make sure you are getting a 107 gasket not a 4.99 they will fit but the fire ring burns out when used on a 107-108 motor ,get some bearing blue and check face to face contact.

Don't get distracted by the Delco-Remy alternator (which is not Delco, or ACDelco) they can be plenty good. The fact that is it Westerbleak Red means it was original to the engine in all likelihood. Video stops at 3:15 into the run, here.

The diode could be a zap-stop, or a kludge to a one-wire conversion, but the fact that it is simply hanging in the air and not secured to any solid surface means it is probably NOT original to the engine. Unless WB did their usual Looney-Tunes design work.

Delco-Remy WILL answer phone calls, and I'll bet they'll tell you the alternator should never have been painted that way, either. They'll certainly be able to tell you what that diode is about, they are engineers and businessmen in the best old-fashioned sense, who enjoy talking tech and educating their customers.

I would replace the motor, The cost that you put out already and still have the problem you could replace it with a yanmar and save money over time in fuel.
