The SS clone's head gasket is starting to weep, so I think I'll replace it before it get worse. It's been 35 years but not a ton of miles since I buttoned up the engine after a rebore and new valve guides. I ordered a flame ring gasket from Old Britts and received a 1MM thick example. I thought the 2mm was considered they way to go, less prone to blowing. Got Jury Duty this week and I'm gonna use my juror pay to get a set of those elastic fluted head bolts from CNW. Also thinking about some beehive valve springs and slippery fork bushings from JS. One Q?; Are the 3 bronze thread inserts required to use the elastic bolts? Edit: Just read it was the .75mm gaskets that were superceded by 1mm, so I should be good with what I have.
