Intake manifold little leak and thermostat must not be level

[Originalowner73 340duster]

Got my car almost up to getting it on the road..after a good warm up I noticed the front of the intake manifold has little leak and the thermostat can't get to seal perfect..can see some bubble coming out...any suggestions on which gasket or any tricks or suggestions on doing intake gasket for my 72 340 motor??

stock thermostat housing?
it may need a little planing to be true

Was ..just bought new all alluminum.permatex high tack sealant on both sides.. and saw few bubbles of anitfreez..funny thing was I ran for like 40 min..and I wiped it few times and by the end it actually stopped..but intake kept coming back after I wiped it ..

Use rtv only. No gasket. Make sure mating halves are flat as pi$$ on a plate.
Drain your coolant
Make sure area is dry when applying rtv. Let sit 24 hours before filling rad back up.
