I normally prefer to use the aluminum framed gaskets (replaceable inserts) from Earls...

But, recently I used the high temp RTV (red) on my header to head and header to down pipe on my '32 Ford and it works flawlessly so far. I think that the key here is flat perfect (CLEAN!) surfaces. Any flaws in the mating surfaces would need a gasket to take up the defects. It wasn't as messy --- BUT I have open hood sides so working on them is super easy... otherwise it would have been "rtv all over everything".
I've found over the years the number one issue with header leaks is the LACK OF going back to snug the blots after some heat cycles if you don't use locking bolts.
I personally prefer the PERCYS Split-Lock bolts. I've never had one come loose after the first tightening.... and MOST IMPORTANT... the shoulder on the bolt is far smaller than the ARP versions which can cause interference on some headers... and they use a smaller head so I can actually get a wrench on them! Tighten them up - and use a hex head to lock - no additional hardware (ugly) like the Stage 8 etc. But it's the shoulder and head size that make them the killer bolt for SBC and BBC IMHO.
