Do your Oliver ones look like the Pro-Gram versions? 
Pro-Gram lists the following contacts/links in the US:
Oliver Racing Parts
1025 Clancy Ave. NE
Grand Rapids, MI 49503
Ph. 800-253-8108

Might want to do a search in the Advanced forum, I believe there is an issue with some splayed caps interfering with the dip-stick tube. Of course it really depends on the brand more than anything else, but I'd imagine the smaller the splay angle, the better the chance of clearance.
GMPP makes some billet straight-4-bolt caps as well BTW.

I have two motors in the shop right now, one has Pro Grams on it and the other has Oliver caps on it.
IMHO the Olivers are a better design and higher quality, but they might give you a slight problem with the dipstick. The Oliver's I am using are a 4 bolt direct replacement cap, so the outer bolts are straight up and down not splayed. So less dipstick problems than a standard splayed cap.

thanks guys !
i will do a search because i am pretty sure the pros-cons of splayed vs straight bolts have been discussed already. but if you have facts, feel free to post them.
