Brian,
You have too much patience with this build. It would be killing me.
You should consider using a punch on the front & rear of the block and on the intake to dimple it. This will give the right stuff something to grab instead of a smooth surface. You know I hate oil leaks.

Anyway looks good!!!!!!

OK, I've seen this a couple of times. My intake on the 92 has been off 3 times so far, each time I put it back on with permatex black rtv (came with the gasket set). I haven't done the "dimpling" and have never had an oil leak. Why does everyone think it needs dimpling to seal?

Brian - great looking build!

I've found that the dimples can help hold the bead of RTV from moving. I had one intake job where the bead shifted back just a little. There was a leak by the dizzy. I was able to take the dizzy out and swipe new RTV into the gap through the dizzy hole. There are some pictures in my thread here: http://forums.corvetteforum.com/c4-t...am-issues.html (so I don't clutter up the thread with pics)

SloRvette

Initially I wanted him to just to do the tune
But my new job has me so busy I decided to let him do it

He really knows his stuff
After spending $200 in tools to put my suspension on, I also figured it would be cheaper in the long run

Looks good Brian. 3 weeks to get the other head and the intake on. Let's get going. Can't wait for startup. Will it be spring?
