HV pump is not needed. The aftermarket cover is a bolt in deal. Build it right either way and your oil pressure will be fine.

TurboBuicks.com - How to build a front cover/oil pump

This is a good step by step guide on porting one. Buy a new factory one from Autozone (special order, but still cheaper than others), or get in touch with FrankG on this board. He sells new ones as well.

I thought the Silver Seal was the only aftermarket cover - I do not know if they are from China but they are not all that great in quality. I have read about porosity issues and my cover has a pocket of porosity that was opened up to the outside surface when they drilled and tapped for the oil pan bolts - it leaks

The cover is not always just a bolt on part when one has a roller cam that uses a cam button that adjusts the end play between the cam and the cover.

I'm thinking about putting my 300K mile stock cover BACK on. I am wondering if I have some porosity in an area I cannot see.

AutoZone The part number for the front cover is 500231 and it's $92.99 plus tax. The brand name is Pioneer. It is a special order item, when I ordered mine they were able to get it within 24 hours.
Pioneer pn: 500231
Clevite pn: 6018091

They are also made by "Greywerks" or something like that. You have to be careful, I have had one too thin to port the oil pickup, and one machined incorrectly for the cam sensor. The sensor sat at the wrong angle and didn't fit!!!!

Also get the Melling P-20I booster plate from Advance for $11.
