[TR] Head Gasket: wellseal or copper spray?

[Brian Jones]

I broke a pushrod recently. Self inflicted - I hadn't tightened  
sufficiently a lock nut on that rod's rocker when adjusting the valves  
a few weeks earlier. I was moving pretty quickly when it went, and the  
noise was startling!
Anyway, I am putting it back together this weekend. I have 'saw marks'  
on the faces of the block and head. I think this was intentional 'back  
in the day' for bite for the gasket, or so I have read.

I have a new copper gasket. Given I have these striations, should I  
use Wellseal, or the copper spray recommended by Gasketworks?

Has anyone used the copper spray successfully on a gasket for a head  
that has an imperfect surface (Its flat, just not smooth)?

Thanks,

Brian
