will LT1 heads work on a 350 TBI swap?

heres the situation,
i got a rebuilt 350 motor, holley intake, holley 670cfm, comp cam, edlebrock heads, and put it all together, runs great until i find it is burning collant and the heads are crap. so i need new heads. if i knew those heads were no good, i would have gotten vortech heads and a vortech holley intake, so what i need to know is if LT1 heads will work on a regular fuel injected chevy 350. i dont think they would with the reverse collant flow. does anyone know where i could get some good heads cheap and complete ready to run? i need this car running soon, and it ran nice and strong right when fired up.
i can get a set of LT1 heads real cheap from a friend.
also is there a big difference between a 305 TPI head and a 350 TPI head? i might be ble to get a set of 305 TPI heads cheap.
any suggestions?
thanks
Joe

 

its doable but not worth it unless you have a machinest in the family that can also weld aluminum.

350 TPI heads have bigger chambers and probably bigger port volumes than a 305 TPI head.

 

As stated above the L98 heads have bigger volumes than the 305 heads. also the intake valve is smaller on the 305 heads.

Vortec heads are based on the LT1 design, only improved on.
