It might sound silly but you can actually put some old spark plugs in there and then smash the porcelain out of them. They fit perfect As for the timing cover seal I would spray it down with pb-blaster or something similar. It will pop out, its just a really tight fit

I used some generic oil pan plugs I found at autozone, worked really well!

There is a local smiley's here that I get mine from. They sell a lot of dirt track parts and apparently Chevy guys use those to repair the block when they mess up the threads for headnote. So they keep them in stock.

the threads on a sparkplug are not 5/8-11...that is just a bad idea anyway..why not go to the hardware store and get the right thing for a dollar a piece...

ACE Hardware, right in the hardware trays. Again, only cost like a buck each.

Might be a good idea to pickup a 5/8-11 tap or bolt, too. Those threads are most likely all carboned up and need to be cleaned before ya go screwing the plug in. Go easy and keep it soaked with some lube or carb cleaner.
