What has a repeat P300-P0301-P0303-P0305 to do with cylinder head replacement need

As Huntington NY Jaguar service department treated my 2007 x-type diagnostic of trouble codes P0300-P0301-P0303-P0305 in February with replacing all 6 coils and spark plugs, when recently I detected this same diagnostic, before taking any other possible ways, I drove to them (from PA) yesterday requesting deeper look into this problem than just replacing parts knowing that they had to cover their first such order with one year warranty.. This morning I got the shocking email from them stating that their inspection found the need for "additional service" (than the one covered by their February 2020 work warranty), specifically that car's cylinder head gasket had to be replaced for which they asked $9,052.96!!! As they previously put in their pocket already $6500 from me (more than the value of this car at this time) it is easy to see between lines that they wanted me to say NO, e.g. to pay for no whatsoever work done just for their $300 diagnosing the problem. Please tell me what would have needed the cylinder head replacement before any "additionally to" work be done and how the replacement of this cylinder head gasket (priced at about $50) would have covered 4.25 hours of work (@ their $190/hr price).
Thank you so very much.
PS actually the alleged number of hours would have been 40 hours, and they invented an additional P0420 code actually inexistent.God thanks, I could get my car back for free

Please forgive my ignorance re STFT and LTFT for Bank 1. They only told me that the cylinder head gasket was leaking, "very slightly, not to worry about" via "very slightly not to worry about low coolant." Car never overheated and their (thank God not charged) description of their finding states:
"misfire evident when engine is first started then clears up slightly ck injector connectors ck connections at ign coils, found coolant slightly low run engine to operating temp found excessive pressure in cooling system perform block test found combustion gases in coolant suggesting blown head gaskets".
Car doesn't overheat, there is no misfire felt, performance was spotless but, strangely enough, while driving car home, I had to press harder than usual the gas pedal, what could be the cause of this pressing harder the gas? Decrease power? But gas use was not bigger than usual.
And worse to worse, about how much could a cylinder head gasket replacement cost if I use a "regular" mechanic (they said God forbid as only Jaguar computer could monitor this replacement step by step not to blow the engine) and how many hours of work? And how mandatory would this replacement be? If without this probably very expensive and, they say, risky elsewhere, (40 hours work needed?) replacement because of this "very slightly not to worry about(?)" leaking could I still drive the car safely disregarding the CEL?
Thank you so much.
