Notice that ^^^ these 302 heads have been Port Matched to the intake manifolds going on to them.

NAPA years ago sold a kit that included some self tapping screws that you screwed into those exhaust ports and then smacked them with a hammer and broke them off. Sounds ridiculous but it worked VERY well.

If you are starting from scratch and doing a complete rebuild, Get yourself a used 5.9 Magnum engine to build.
No substitute for cubic inches.
They are dirt cheap and really just need a good cam, valve job, intake, smaller carb,headers..
Easy 300 hp +. Just need to convert from the serp belt drive to a standard 360 timing cover and cam

Look up Mike at B3 rocker arms, if your going to upgrade. He has experience with all the aftermarket units and can lead you in the right direction.
I bought a set of PRW rocker arms and shafts. In the end they needed to be cleaned very thoroughly. There was a lot of metal dust in them from honing the bushings.

I'll have to ask my Napa next time I am there and see if they have them.
I have boxes of them from teardowns. Most Mopar enthusiasts do too. Couldn't be much at a dismantler in Az. Reach out on the message board.

Oil pump pickup screen do you guys have any advice on getting all the oil deposit out of it? I was thinking of leaving it in gasoline or diesel overnight to break it all up. Unless you guys have any advice?
Rock auto! there is always some debris/carbon left...
soak it in 100% pure pinesol.
NB a quart of the stuff will set you back the price of a new pick up
how could anybody tell? there's no frame of reference!
if you had a gasket overlayed it would be more informative and understood. here, this is just a picture of an engine with no context.
roller rockers would be the LAST thing i would buy for this type of build.
your stock rockers will be fine.
there's wayyyy better stuff to spend $300 on

My dtm senses are tingling 
Do you happen to have a part number?
Your stuff always looks SO clean and so nice.

i’ve got OEM 318 and 360 LA hydraulic rockers. I can look and see if there’s a part number stamped on the left right.
As for the oil pump pick up, it depends on what oil pan he has.

That's everything gentlemen that's been cleaned up and being used back onto the engine. The timing cover and water pump is brand new. I was going to steal the main cap bolts off my 73 318 block since that's getting ARP main cap bolts, I figured ARP main cap bolts should do me justice on the drag strip.

73 block up top

You need to use the the 6 3/4" pushrods > roller lifter engine pushrods that work with the roller engine stamped factory rocker arms and roller lifters.
Not the longer 7" pushrods for the small block hydraulic cams.
__________
The 302 heads that are made for the 318 roller lifter engines have larger pushrod holes that allow the pushrods to swing without rubbing with the taller standing roller lifters.

Your '87 318 roller Truck engine came with the factory 9.2:1 cr flat top pistons. Good to use those, and they are already balanced with the assembly.
Aftermarket pistons have a lower compression height coming in closer to 8:1 cr like your '73 318 engine came with.

I wish I could reuse the pistons, but there holes in each side wall on the pistons? What's the rpm range on the hydraulic roller cam if you might know?

If you can see it there 2 hole down below the side skirt?
Can you point out the holes? I see nothing wrong here.
