I'm not entirely sure what you mean by this. However I can tell you that if you have oil in your coolant it's probably a safe bet to say that your headgasket did not seal properly. You should do a leakdown test. There are a lot of reasons this could happen. I'll name a few.

1. Reused head bolts
2. Warped head
3. Improper torquing of head studs / bolts
4. Uneven deck surface on block
5. Using a MLS gasket with improper prep work
6. Cracked head / Block
7. Dirty threads in block where head studs / bolts go in.

Reused ARP studs
Not sure if head is warped
I started from the inside out 30lbs 3 times criss crossing 30-60-90-93
Head been decked
I used MLS for sure but I cleaned both surfaces
Block dont seem cracked nor does head
But thread being dirty maybe a aspect

Definitely do a leak down test.

You have to deck the block to run a cosmetic or any MLS gasket

I only ever run mls and decking a block isn't exactly easy now a head is easy but a block I just clean it up good

You seem to blow a gasket every time you touch the car

The 420a runs a MLS headgasket stock. You do not have to deck the block.

You do if you want to run an MLS headgasket to ensure an even surface.

Only if the deck surface isn't flat. The OP should have confirmed this before putting on a new headgasket.
