Engine and whole car shakes

my engine and whole car shakes, no cel. it also smells gasoline very bad. i can hear sounds like valve work from exhaust, i tried to listen with wooden stick engine block parts here and there no sounds at al beside the sound fromnexhaust, i opened the valve cover, no broken valve springs, all pushrods spin around. i ve been to injector shop he checked all of them on stand and on car and said they work no problem.
the engine block is quite tilted backwards 10°. what direction i should dig? here is a foto of engine mount i think is tired.

can i check the valves without taking off the head? if i take off intake manifold and check/clean with carbon cleaner the back cap of valves? if they are leaking

I'd probably check the exhaust manifold/headers to ensure you don't have an exhaust leak.

I'd also check vacuum lines to ensure you don't have a vacuum leak.

Are your spark plugs good?

Do you have good compression?

Not related to the smell of gas or ticking valves, but I'd also check your motor mounts if the engine moves more than it should.

no, i didnt do compression test as it does not consume oil. i changed all sparkplugs, cleaned the throttle and the sensors that monitor throttle

Do you have your o2 sensors installed? Seems like I remember you were pulling your cats off in a previous post?

yes, they are in, my exhaust is federal, since the sound was coming from exhaust i thought something is wrong with catalysator, i took it to check, only 2-3 honey combs are plugged overall looks better than new korean car cats.
taking off the the exhaust pipe was more difficult than tranny swap or when we swapped honda engine on different car
i broke all exhaust bolts
