Dipstick with problems

[mblackburnjr]

Recently i swapped the motor out of my 71. The p.o. had installed a later model(like '84) 305 out of a monte carlo.Manifolds and all. When i dropped in my old 350 (like 73) the drivers manifold sits right against the dipstick hole...I plan to run some headers eventually, but right now i cant bear to cut the newly run exhaust he had installed since its a daily driver....so my question is....whats my options?..fill up the hole w/ silicon..lol...
