|   Daryl,
  Yes, I'm using Total Seal gapless rings on my 3.2L engine in my 240.  Even 
though they're expensive, I'd highly recommend them.  I've been running my 
engine HARD for the last 3 years and my compression level is still good on all 
cylinders (140-150psi).  They take a little patience to get them set up 
perfect, filing, measuring, filing, measuring, but I do think they increase 
compression and performance.  I think I paid $130 for the set.
  Top End Performance (who I bought mine from) uses them on their crazy 4-500hp 
turbo L series engines.  So they can take a little abuse.
