My '68 LeSabre 350 4bbl is, as far as I know, stock. The engine was burning massive amounts of oil, so as a stop-gap while I save up for a rebuild, I'm putting in another 350 short block from a swap meet. That engine came with different heads which wouldn't bolt up to my exhaust, so I'm using my own heads. While installing the heads, I notice the dipstick in the new block uses a tube- mine went straight into the block, no tube. Problem is, the tube points directly into the stock exhaust manifold with my heads bolted on. Also, I don't have the actual dipstick, just the tube. Any suggestions? Heat/bend the tube? Is there some more generic tube/stick combo I could buy that would fit, or could be bent to fit? I'm happy to post pictures and/or part numbers of what I have if that's helpful, but I'm at work at the moment.
