If you can catch a finger nail on the carbon ridges, they will have to be reamed to get the pistons out.
Be advised, however, that it's extremely easy to take too much material when using the ridge reamer. I made that mistake on mine. My machinist told me that my cylinders would not have needed boring had I been a little more careful removing the ridge.
Wow, thanks, so if you remove too much then the piston won't seat or will the compression be off?
I just called the machine shop:
Dropping off the block on Monday.
He will hot tank the block-60 bucks.
Install cam bearings-44 bucks, plus he is buying them so I get the right ons.
She has to pull the pistons (we are both learning here on this part) and Cam. Good time for a rear main seal as well.
Question on RMSeal. Do you apply any RTV or to the seal. I replaced on one time and it leaked. Then one day we had to pull the old motor and I couldn't get the seal out-I used Super 300 black on it and since the block was junk, I use a screwdriver and still it wouldn't come out. Never do that again.

As long as the reamer takes metal out above the travel of the top ring, it isn't a big deal. Taking just barely enough out to get the job done is always best though.
I've always had the best luck using a dab of gasket sealer (not RTV) on the rear main parting lines. I've offset the parting line from the main cap before but that's probably silly. What always concerns me when using an old crank is whether or not there's a wear mark on the journal where it contacts the seal. If so, it doesn't usually matter how you install the seal.

OK thanks everyone. A little gasket sealer etc and check the ridge first.
The machine shop said I need to remove the pistons/crank, so I thought while at it, hot tank that baby.
Question, (sorry guys-you might be getting tired of questions). When she removes the crank and if a bearing is scored, can we just order new ones or does the crank have to be turned (if).
P.S. When done, I just might swap her my 360 !!!!!!!!!!!! But she won't go for that. At least now she will know about tearing down an engine-thanks to you guys.
I asked her to read this thread as well. She's been very busy at work and I'm trying to help her out.
