    I have no experience, just what I've read, some say the bump in compression with the bathtub chambers isn't worth the problem with the valve shrouding because of the shape of the chambers. ive got 063 closed chambers, 292s like you have a a few 781s for my el cheapo flat top 454 re ring build. jim
