I use the 1037's as well. Never had a problem.

Not sure but the 496 is likely a Mark VI block. Are the gaskets you have for a Mark IV/V? Their are likely differences.

The 1037 is noted as working with all Gen 4 Bowtie/5/6 blocks. I do have a set of cometics that I ended up not using if your interested. $150 and that includes shipping.
