I noticed the 217 and 218 are the same length in your list, but on the post above they are 10mm x45mm and 65 mm. 228 are also 65mm but have preapplied CTG??? I would go to a big truck dealer or an industrial supplier and get flange headed bolts in equal or better grade. Probably a buck apiece at most.

The threads in the gm bolts are rolled differently so that they maintain the clamping force but allow the manifold to expand and contract from heat cycling,the normal bolts don't behave in this manner and you will most likely have trouble sealing the manifolds over time.

A good move would be to have the manifolds planned straight while they are off and then no gasket material would be required.

Aftermarket gaskets get scraped off when the maniflods expand and contract-in a worst case scenario some high temp silicone might help with sealing when the manifolds are to rotten to keep the ports covered.
