The late small block ones have the big seal that goes on from the outside, but since he didn't mention having a late cover, should be fine.

It looked like they would fit. Is there a trick to installing one into an aluminum cover? I don't want to crack it trying to hammer the seal into it? Last edited by RoadRunnerJD; 04/18/10 09:18 PM.

I've got something the correct diameter around to drive it in...can't remember where I got it from but even tapping around and around it with a drift will do as well.

I've never put a seal in a late small block, only big blocks and early small blocks...but have had the late SB covers around at least to know what they are like Late cover on the right, and magnum on the left.. 5933780-012(40).JPG (48 downloads)
