I'd say if your doing a build above 400 ish it's a no brainer as it is part of gaining reliability and why not as if you going for power and spending good monry why skip the important bits . I remember Karl Norris doing a write up on 500 bhp engines and said standard bolts are fine as long as you change them every 3 to 4k now I don't like that idea as steady hs already mentioned ever bolt is different and what if the clamp isn't as tight as previous and you are still clamping at the top of the block
