14's can be done but I would read the sticky at the top of the page devoted to TBI newbies. It should tell you what go fast parts you need to consider.

its all going to be in the cam, with a 4bbl intake, a 670 TB unit, ported l98 heads (the only issue here is compresion, what are you going to do to make up for the compresion loss?) with descent cam, and proper tuning, 14's is easy, i am pretty confident my combo will run 13's.

i think that is a better match for your combo than the L98 heads, if there is a flow diffrence (i think the ports are the same on both) the compression diffrence would make the 305's the better choice.
