This thing had some nasty flashing inside and out side ,I smoothed all the webbing smoothed all sharp edges and took down the out side flashing just because they were nasty . De bured all the main journals deburred the main caps

I dunno man. It looks pretty good right where it is.

Clean up some branches where the fence portion goes and put it [around] the trunk.

Very cool progress thread, and sorry about the tree… it’s best that it fell now and not when El Niño touches down!

Funny story - the first time I had my 302 apart I ended up putting all of the rod caps on backward. It took me a minute to figure out why the engine wouldn't spin on the stand before I figured it out. I realize it's not your first build, but it happens to the best of us regardless! It's just one of those moments you can have a laugh at later - which a friend of mine still has every time we talk about it.

I have another set of CJ heads here ,they are in great shape but the exhaust side is strange around the ports. It's about 10 thousands deep around all 8 ports ,almost like it had ran an oversized exhaust gasket and it burned into the surface . Now I see no reason that surface couldn't be milled about 10 thousands ,anyone see a problem there?

They're steel so, probably won't be an issue. While you're at it, measure the depth of the bolt holes so that you don't get surprised.

Three pass through ,the fourth is about 3/4 so header bolts through the exhaust flange should be no problem. I already ran a tap through to clean them out ,390 and 428s are bad about welding in exhaust flange bolts and not fun to remove when they snap off trying to remove them . I will take them in Monday and see what it takes to clean them up .

Probably wouldn't be an issue structurally, but machining them flat again would ensure the best possible scenario for your new gasket to seal.

Atta boy! I mean it's only money, right?!


Seriously though, I know that feeling. Sometimes that's all we can do when stuff pops up that's kind of unexpected and out of our control to try to derail our plans. We stick to our plan.

I took the exhaust side to a 36 in table type belt sander ,I could probably get it all out but don't want to go to far with them ,I may go a bit more but we will see. The copper header gaskets cover everything so I am sure they would seal as they are .only had 180 grit but 80 would probably knock it right out ! I kind of think they were running gaskets that were to big for the ports

That's odd because even the stock gaskets are to big and these are the 6090 CJ heads. I will have to compare them with my other set but I know they are right!

Well ,my fresh heads ports line up with the gaskets a little better ,they are all 6090 N heads ,i don't think the first set has been ported ,although the fresh set are over the counter heads so maybe ford did somthing different with the ports .the first set is the set I would like to run after some clean up because the y are set up for a higher lift cam and they actually only have about 1,000. Miles since a rebuild so i figure I would break them down and clean them up,they just sat in the shed for about 4 years .
