I removed 7 12mm hex head screws and 4 addt'l 12mm hex head nuts. Is there any others I need to remove? I read there's two allen head screws as well but I cant seem to find where they're located. Piks would help or a lead to a good thread. LMK and TIA.

 

The Allen head bolt is just about under the thermostat housing looking from the right side of the engine

most times if it was never apart it is full of dirt making it hard to see.

It takes a 6mm allen wrench

 

Thanks for ur response. I found it and then went at it. Is there just that one or is there another one hidden?

 

Just that one being the manifold has been on since the truck was born more then likely it is stuck .

Some tapping or the use of a small flat pry bar is needed to break things loose just don`t go wild and break out the 10 pound sledge hammer

 

Ok thanks I got it off and now gona do some carb cleaning. Any advice on good and fast cleaning solvents & cleaning tools and tips?

 

I find Gum Cutter works Good.

Another Good one is Kano Labs Floway

Dish washer for the parts that can be removed.

Pressure washer if one is careful around the electrical parts.

The small nylon brushes work wonders.
