What's up guys, so I'm curious to see what u guys think of my deck surface for Cometic MLS head gaskets? Hopefully some1 can tell by the pics I post?

History is, I measured deck height and instructed the machine shop to square up the block. Machinist said he did not recommend decking the block after everything was finished and I went to pay and b pick up. So I picked everything up and cleaned, de- burred, and washed the block twice. Not realizing the smoothness I need for the head gaskets.

B4 I finally assembled and washed block for the 2nd time I went over the deck with 400 grit wet sandpaper.

Here's the pics, maybe some1 can see if I need a smoother surface. Thanks for any help on this...

 

The surface looks fine as far as can be told from pictures. Shouldn't be any problems.

 

Cool, thank you!

 

From memory as it was 8 years ago, I used 400 grit on my deck. I was fortunate enough to borrow and Ra meter from work and found the surface was typically below 30 Ra so you should be OK. I would also recommend using Hylomar on the Cometic gasket. Hylomar was originally design for turbine engines and it works really well. Its a little hard to find but worth it in my book.

 

I was searching and I came across your thread on this so thank you as it was very helpful!! I plan to use the hylomar or copper spray as an xtra precaution.

Where can I find the hylomar spray? Online, or maybe an auto parts store? I don't remember ever seeing that kind of spray at any parts stores?

 

I think this is it.
