Should of heard some of the comments on the initial thread.. I was rolling on the floor laughing despite having a big issue with the mixture. That issue has been fixed. Now we're working on a rebuilt engine with great compression, poor pulling power and an ignition ping at 10 degrees timing. I'll set the timing back to 6, maybe even 4 and we're looking at a suggested cam.
We got the old sinker off of the top end today and began a quest for the cam. I talked with Summit who went a bit more conservative then you mentioned. So I figured I'd call Crower. I was pleasantly surprised when Mr. Crower took the call and asked me to send my cam into their shop, they'd I.D., and analyze it - providing their recommendations.
THAT's CUSTOMER SERVICE! Thanks for the lead Dragon!
I have a month to have this project complete and the truck parked so we'll decide in the morning on what route we're headed with the cam.
As for the intake, I'll clean the surfaces and get them ready for the install. Overall everything is clean except for the back of the valves. There is a good bit of carbon built up. I'd imagine this was left over from the time had the rich mixture..
No Problem. I like Bruce and his son. The video I did for Crower is on my Mac and after I get it up and on the net I will post it. My monitor was stolen.

I began cleaning the head surfaces this morning and have a question, well a few.
Is the third port from the front in this picture an exhaust port used for heating and vacuum? I am not planning on sealing this port as I will with the water ports.
How do these look after the first cleaning?? There is some pitting around the water ports which I will not be able to fix without removing the heads and having them planed.
Thank you for all of the help so far!

Seal around the heat crossover passage and really seal around the water passages. Triple seal the front and rear intake seals. The crossover passage is there to heat the manifold and hot exhaust is the next to last thing you want inside your engine. Sloppy sealing around the water ports is why the pitting. It also might mean at one time the engine had water in the oil. Probably long before you got the truck.

I redid a picture for the post above. These are the three port we're referencing, the front and back are the coolant ports.
I may have to fore go the cam for now. I have a month until I head to TX for a deployment to Afghanistan. I'll call Crower cams Monday and see how quick we can turn this. Plus there is always the $$ and wife factor here..

My feelings exactly - FT Hood! Do not get me wrong, Texas does have some nice points.. I have about 4-5 years at Hood and we really enjoyed Austin, San Antonio and Corpus Christi.. Just could not get away much.
The Navy had me at Beeville NAS Chase Field 73 to 76 and I enjoyed the same places. Street Road Races in Austin GTC class 69 Camaro Gymkana suspension Ford RUG 4 speed 396 510hp. 160 top end 0 to 140 in 14 seconds. Fun place to be race practice on the Farm to Market roads at night.
I spent a bit of time growing up at Ft Hood I turned teenager there and I started working on a race car there when I was 13.

Right at the corner were the head meets the block is a major leak point. Put sealant on the metal up the head to the valve cover surface and all the way across the front and back edge of the block. Put in the intake gaskets with the other places sealed and then the end seals. Then you do the same to the top of the intake and over the top of the end seals. The end seals need to be set in with something that won't let them slip, Right Stuff or 3M Weatherstrip seal. They are notorious for slipping out of place when you are putting a manifold in by hand.

The new cam should be here tomorrow or Monday.. I ended up going with the Crower 16915 and a set of their new lifters. In all of the discussion, Bruce recommending a pretty conservative cam, Dragon yours was the strongest, and then DJ at Crower was pointing to one size lower from your suggestion which is what we went with(these things are like shoes when it comes to preferences!! ) They also have some new lifters that have a small flat spot or channel in them to let oil flow through the lifter area, an interesting idea which we went with.
Is there anything I need to do to prepare for the installation?? The old cam was in great shape so I should be able to leave the cam bearings alone, yes?? Other than this I have all of the surfaces prepped for gaskets..
Thanks
Dan
They sent you to the Baja Beast Master and I was recommending the Power Beast. Both very good cams. I don't tow but I want torque so they recommended the power beast for me in 1979.
I built an all Crower motor one time cam, crank pistons, rods and valve train. Edelbrock 2 4V manifold with 2 sideways mounted 950 3 barrels Accel Dual point.. That 432 ran 8.21 at 149 and I used the rods and crank in another motor a year later and had no problems.
just clean it up and be careful you don't ding the cam bearings in all the in and out action.
