H1/H4 Conversion question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just completed converting my 86 to dual headlights so now I am looking at installing the H1 & H4 conversion bulbs I have.

The stock 2 pring headlight plug will not connect to the H1 headlights I have. The spade lug on the housing is about a 1/4" lower than the spade lug on the actual bulb. I know I can fix this by cutting the factory connector off and using crimp on spade lugs. Is this normal for H1 bulbs?

The stock 3 prong connector fits the H4 headlight with no issues.
