I went with gapless rings on the last 306 I built and I really like the things. I used the Total Seal two piece rings. The two top rings are both gapless. Each ring is a two piece design with each piece having to be gapped same as standard rings. All you do is stagger each set just as you would for the top and second ring. It's a little more tedious than managing the gap placement of a standard set of rings but worth it I believe. I was kinda leary of stacking two rings in one land but it was really easy to install and I haven't had any problems with them for a year of hard running and they seem to have every bit as much "pop" to the cylinders as always. I wish I had something to compare them with but the engine was all new and lots of changes took place during the rebuild but oh well, maybe next time.
FYI, I am putting them in the 351-C I'm building for my next project. This one will be pretty much the same as the previous one but with a roller cam and roller rockers. I'm shooting for 400-450 horses but time will tell. (400 should be easy to come by but I don't know about the last 50)
