I would put some green slime or dielectric grease on the carb, backplate, and needle o-rings and run it. It's very rare to get a new engine with an air leak, but checking for bits of metal on the inside is a great idea. Rtv is messy, and I won't seal anything with rtv until it shows symptoms of a leak.

IMO the rtv is too messy, but if you get some lucky seven engine sealant you can simply apply it around the backplate and other areas without taking your engine apart.
 
i havent done mine yet (hoping mine turns up in the next week) but apply a thin layer around the back of the motor where the backplate touches. when i say think i mean less than paper thin as the more u use on there the more that is gonna go everywhere and u dont need or want that. and not sure about the carb neck and i think associated green slim is best for the needles as u dont want that getting hard.
 
BP sealed, Tiger Drive, F. Wheel, & C. Bell on. forgot to get carb sealant but, will get it tom to seal it as well. I sure hope I did the BP sealing good enough, I used a darn tooth pick to create a small bead to minimized over apps. Pls let me know what's your take on the seal job, thx in advance folks.

Yup, looks good. Did you look around inside the engine for any stray metal bits?
You can get dielectric grease just about anywhere for the needles and carb o-rings.....it's just silicone grease. I would take some rtv and cover up the carb pinch bolt too.

Thx for the good comment. Yes, I took heads off felt inside the sleevs, look around & even gave it a good burst of air. I did not have time today to seal carbs but will do it tom, would you mind sending me pics of the carb sealant you're talking about, I will seal PB Tom as well. Thx in advance.

Permatex copper RTV sealant, any auto parts store will have it and it works well too.

Is it like a grease type sealant without it hardning? I just don't want to use the kind of sealant on Carb that sets & hardens. thx in advance.
 
How tight do you torque down the head bolts on the block? (5 Soc head cap screws) thx in advance.

I am fixin to test fit the banger on the truck, will take some pics.
 
I use a round handle 2.5mm driver and almost as much torque as I can get on it with that tool. The important thing is to tighten them evenly, a little at a time.

I would say it's mainly from being a new engine, but it's good to hear you got 'er runnin good. Now it's up to you to make it run like that for 5+ gallons.;)

I hear you on that. Now that I have you folk's more input, it's just more bullet for me to use if these thing acts up on me. :D You guys are awesome, keep'em coming.:first_place:
 
Yall ever here of Hylamar, made esp for Rolls Royce, should be able to find it on a search. Used where there are two flat surfaces with no gaskets. Use VERY sparingly RTV has its purpose but not on these engines, I would use soft Permatex before I would use any kind of silicone.
