Oh sorry I wasn't very clear. I am definitely going to go 4 bolt but what I was asking was that since I have the two bolt block already should I go ahead and just install splayed 4 bolt caps and go 040 on the bore. I plan on using a Lunati balances rotating system. It will be built with all the strength needed but I was just wondering about if I should waste my time with this block or just find a 4 bolt core to use. I have heard that ading splayed four bolt caps to a 2 bolt block will be stronger than a standard 4 bolt block. Is that true? And is it ok to go the 040 on the bore?

Thanks
