Not sure if Ari measured that SBC; but I just measured a 304 and it is around 45mm lifter to matched lifter. (hard to reach spot so not precise, but quite close)
I also note that Roller rockers (pedestal mount) are the same on a 304 as they are on a Pontiac 455.
Also I have heard that Harley Twincam roller lifters are the same as SBC lifters. I happen to have a set of H-D TC lifters and I just tried them in the 304, they slip perfectly into the 304 lifter bore; although any more than about 0.100" lift and there is risk of losing oil feed to the hole in the lifter.
