Wow, that makes sense. The mags couldn't explain it to save their lives!!!

Have to love Tech articles

Ya, it's easy

Also, summit carries it in stock.

Well, dad and I got the timing chain off, the oil pan off, and then we used an electric drill with basically a scotch pad to buff off the head gaskets and the timing cover gasket. I also went and got a honing/deglazer tool from Murrays for $30 and we honed all the cylinder walls. When we got the oil pan dropped and turned the engine over we both agreed that everything seemed to look really clean and there was no sludge in the oil pan, so we decided we're not going to worry about replacing anything on the bottom end. We also decided, after looking at my dad's Formula enigne bay, you can't see any of the block so we're not going to paint the engine block afterall. We're still going to paint the intake manifold.

So, that said, we're almost ready to start reassembling the block and do the cam swap. Two questions though:

1: Can I use regular engine oil to grease the cam shaft when putting it in, or do I have to use cam grease?

2: What type of gasket sealer would you guys recommend? We've got all the gaskets just not sure if we need to spray something or apply something to the surfaces before putting the gasket on.

Piccccccccccccccccccccturrrrrrrrrrrrrrrrres!

x2 on the pictures, and you use stuff called assembly lube on the cam when you install it.

Most certainly.

Yep gotta use assembly lube on the cam, at least thats whats recommended. As for the gaskets other that the suppplied stuff, if you need it, use some red high temp RTV silicon sealer. For the rocker studs I always use liquid plumbers tape. As for the head gaskets they just go on by themselves and make sure you torque everything to spec with a nice torque wrench.

Get some STP in the blue bottle and use that when installing the cam. Forget assembly lube.

Is there difference between the red and black RTV silicone? I think the master engine gasket set I got came with black.

As long as its some high temp stuff you should be fine Brian.

Both are fine. Red sticks out, though. I'd go with Black.

Um, this is just my personal opinion/preference but if you ran a hone inside the cylinder walls then you are going to want to remove the pistons and clean them off from the dust you created.
You don't want any problems.
You have minimal clearance between the walls and steel dust, Alum. + heat will gall and then you have problems.

So, that said, we're almost ready to start reassembling the block and do the cam swap. Two questions though:

1: Can I use regular engine oil to grease the cam shaft when putting it in, or do I have to use cam grease?

I use assembly lube, greese has no buisness on the inside of a motor.
Then after you run the motor for about 100 miles, drop the oil and put new in, it helps clean out the lube.

2: What type of gasket sealer would you guys recommend? We've got all the gaskets just not sure if we need to spray something or apply something to the surfaces before putting the gasket on.

Ultra Black RTV, it's O2 sensor safe.
Not all high temp stuff is, just make sure if you buy any you read the pkg before you buy it.

It seems like we got all of the dust out pretty good - we wiped the cylinder walls down with the rag and then as each piston went to TDC we got all the crap out.

Here's the progress pics:

Cool pics B. Thanks for the visual update, haha.
