Default Cam chain clearance to block

I just put on a Rollmaster CS2090 and it looks super close to the #1 side of the block. I saw a note in the box that some grinding may be needed so I guess this is what they were talking about? No marks or scraping sounds when turning over to degree the cam.

Can you push it towards the block and cause the chain to make contact at any point?

Hard to tell. Iíll try to stick a feeler gauge behind it as I canít tell if itís hitting the block or sprocket. Is this a common issue?

I can't answer that question but it definitely looks close.

I guess if they send a note in the box their product has clearance issues in some cases. that really blow's who wants to grind on a new build

A little annoyed about grinding on a fresh engine and will have to tape everything off like heart surgery. I guess the trade off is that it *may* fit under the factory cover (itís a lot easier to grind/replace the cover though). Otherwise itís a really nice set for the money. Installed the cam straight up and was within a half degree of spec.
