Thanks for the responses. Due to kids activities been away for a while. Got the frnot clip off and por15 in the engine bay and underside of hood. Got a new radiator ordered today from champion radiator in CA. Got new aluminum fuel line put in from new under the bed tank. I flushed out the engine quite a bit until i got clear water coming out but there was alot of rust/scale. I saw champion radiator has an inline coolant filter that goes on upper rad hose that i think im going to get as well. Also saw on youtube a guy used screen material and inserted it in the upper rad hose to catch any particles. Think i may do that and run several times once new rad is in so i dont clog it. Any thoughts?

Well since the last post i tore off the front suspension and ordered new tubular upper and lowers with stock height spring and shocks from performance online. Everything came off with old hand tools thankfully. While the old front suspension was off i used the POR 15 to coat anything I could reach around the engine bay. Got the new tubulars installed and looks good. Now just have to save a few more pennies for the front discs, booster, master, por valve and brake lines. I havent looked yet but is anyone familiar where i can get vacuum from the intake for the booster. Like i say learning as i go and i think i have watched every video on 305 v6 on youtube. Really wish i had a shop to work on it in but the old backyard works.

There is a plug on the back of the intake manifold. I bought the fittings at Home Depot. If you are planning on removing the intake manifold be sure to break the plug free first, it is on very tight.

Thanks for the picture!

Looks good! I think it's a federal law that you MUST put por-15 over the openings to your zerk fittings when you smear it around the suspension though.

Had a setback. Psgr side head front freeze plug started leaking. Once i got it out the inside of head was completely clogged with rusty scale sludge. Guess thats what happens when u leave water/anti in engine and it sits for about 27 years. I had flushed alot of crud out but when i saw inside heads i pulled them off. Soaked clr in coolant passages of heads and used flexibe bore brushes to scrub inside. Pretty clean now

Put a strait edge on block and heads and nothing warped. Buddy said while heads off to do a valve job so i may be learning how to do that soon.

After much frustration with purchased valve spring compressor tools, I made my own. It is useful for stem wiper and spring maintenance without head removal. It does require spinning the nut onto and off of the rocker stud a few times, but with a "cow magnet" and an arm, the keepers are removed and installed with some ease. In your case, the store-bought tools will easily work.

I missed this post from last month, I have encountered this situation in the past on these manifolds, plugs or fittings after many years they're frozen on there so take a propane or map gas torch and heat up the plug or fitting and it will come off a lot easier

Thanks for the advice. Had a buddy with spring compressor tool and all came off no problem. Took heads to machine shop and put in vat and tested for cracks. All good. They recommended using evaporust in block and let sit for several days to get that cleaned out as well. Took apart the rocker arm assembly and had alot of sludge so got that cleaned as well.

Been awhile with kids activities but slowly getting stuff done. Got the engine back together and fired right up. Got the front springs, spindles, and brakes on. Got the booster, master cylinder, and proportion valve on. Have the new brake lines in but not connected yet.
