Yeah, the issue I had is that parts store people are generally ignorant.....the size was standard but since it wasn't listed in the "computer" they didn't have the common sense to look it up in a real BOOK.
Brass is better than steel....steel is standard used in production blocks but corrodes where Brass will not corrode like the steel will. I used steel in the one we just did because I didn't have the time to wait to ship some in since they aren't always stocked. Any performance build you will see Brass used...just a better alloy material. Your machine shop should have them in stock if they do any amount of work for guys doing performance build ups
