offset lifters

do i have to use offset lifters when i have bae 5 heads on a old -0.500 kb block 1.800 lifter space to compensate for the 0.200 missing?And what lifter brand is considered the most durable?

 

I was researching using a fuel block with Brad 5 heads and ran into the same question. Crane has the lifters, don't remember the part number. I called several manufactures and very few made the offset lifters. I gave up on this idea because the way I understand it a fuel block is a 4.80 bore center (NHRA TF Rule) and alcohol blocks are 4.84. If I am wrong, someone please tell me, because there are all kinds of billet fuel blocks going for a lot cheaper than alky blocks.
