Hi does anyone have any good advice on ring end gaps for 1969 block 351 windsor. Keith Black .030 hyper pistons , Hastings Racing rings, 98 octane fuel , 11:1 comp ratio , Alloy heads. I have been told 18 thou top 20 bottom. Just want some other opinions before I file them back.

On a performance engine I would gap a little more . I am running.030 top .032 bottom with CPs . Little blow by on turbo motor . Pistons are gas ported .. Built back in 2002 .
