Default d15b7 blown head gasket

Alright first off don't flame me please I have searched and searched but can't find what I'm looking for.
I bought this 93 Civic dx from my step dad. He got the car dirt cheap and drove it around for a month overheating due to head gasket failure because he didn't believe me that it was the problem. Finally he let me replace it, I did everything by the book. Ran great for about 2 weeks then boom blew again. I told him this was possible, warped head obviously. He was driving one day, shut it off to run in a store, came back out it wouldn't start. Now it won't even turn over. I havn't gotten a chance to tear into it but I'm just wondering what I should even be looking for. I'm alright with engines this just isn't an issue I've dealt with.. Engine seized maybe?
Any info would be great. I'll be able to update with info and pictures of the internals soon just trying to get a jump on it.

Blown head gasket doesn't mean the head gasket is simply no good and all you gotta do is put a brand new head gasket on and you're good to go.

You either need to have the head machined at the very least or you need to have the head professionally fixed by having it heated in an oven and straighten back out in between two pieces of steel.

See that's what I was thinking. I just found it odd my parents saying the car wouldnt turn over and I walked them through checking grounds and stuff. It was driven a lot with the head gasket blown and overheating but like I said it was turning over but not starting and then now it isn't turning over at all. Seems like something unrelated. I guess I'll just have to tear into it. I'm hoping I can get it back on the road with new gaskets and a little head machining. My step dad was gonna scrap it but called me first. Gave him $50 over metal weight. $200 for a straight body clean title ej1

Head gaskets fail for a reason, you must understand the method of failure.

Overheating will warp and twist the head relative to the block, which can result in a leak, internal or external.

Bolts that do not have sufficient clamping force can result in a leak. If you have torque to yield bolts, they MUST be replaced when the head gasket is serviced or else you risk another failure.

Antifreeze that has become way too acidic will eat at the gasket, and cause a leak.

In rare cases on a stock motor, over-compression and pre-ignition can reduce the durability of the head gasket.

Examine the cylinders that are washed out with antifreeze to determine the point of failure, after that all you need to find is the method, its one of those four.

Thanks for the good info man. I'm pretty confident that the head needs to be machined. But I wasn't aware of the need to use new bolts so that very well may have contributed.

Well swapping is an option of course. The only issue I have at all with swapping is what to put in. I am hung up on whether to go B16 with bolt ons and call it good or spring for a little more and turbo build a D-Series. But either way that leaves me with the issue of what to put in now because I dont want to drop in a d16z6 or something just to pull it back out to build but Ill have to save a bit for a b16.
