[Roadsters] Info: Replace gasket between head and engine block. What, how, major? Not a job for old fart?

[Charles Vanderburg]

Nice little SR311.  While complete update with new parts, found leak in gasket
tween head and block at 2500-3000 rpm plus.  Anyone knows what is involved?
Big time?  Major?
No leak at idle  .Sounds like big job!  If interest, reply or call
