I have about the same. Standard bore block with mismatched caps for $100us. I found set of two bolt caps from an R block for $100, so I'll go through with a line bore and such. Looking forward to your progress.
Honestly without caps they are really only worth $100…especially in Canada as machine shops probably charge $500 for a line bore…so you could end up with $1000-$1500 into the block by the time you are ready to assemble
