2 answer your question....YES!!!!!

Make your car fast and the motor wont matter. Ive seen 882 heads pull 3-5 car lengths against unruled aftermarkets.

I ran 416s (1.94/1.6, 60ccs) with stock rockers and switched to S/R torquers with Comp rollers. I COULD FEEL THE 305s pull harder, but the S/Rs had more top end.

305 HEADS ARE LIGHTER THAN CAMELHUMPS!!!!!

Put each side by side. Im a lying? no. LW front means you can turned quicker for seemingly even more bottom end.

One vote for the 305s!

If you can grind on your intake, I got a cast iron down to 26 lbs (stock is 37-39 or close) Aluminum 11-14. It adds up.

I ran 6200-6400 rpm

With a bunch of port work and combustion chamber work, the 305 makes decent power for a 2 barrel engine. I watched a pair run 3rd at the IMCA Supernationals in a qualifying race on top of a simple 355 back when everyone ran the 350 carb. Just takes a lot of work. There are other plus's to the design of the 305 such as plug placement.

you can get dubble hump heads from 100 bucks on up to crazy money on e-bay crigslist an such..an new casting are available too

you can get vorteck heads as cheap in same places or junk yards an new from aftermarket too

i dont see puttin all the time an money in a 305 head when there's easier,cheaper,an better alternatives easily available!

Answer is.............Yes you can!
I ran a combo almost identical to the specs you have given here.(different cam)3400 pound car with 2 barrel and street tires.
I did do some work to them to make them flow better than stock. Also retained the 1.84" vaves too.
Won over 30 features with that engine, against 406's,377's etc. Never had to twist it over 6200.

the 305 head WILL WORK!!!! i have seen it. i have done it. i know what works for one might not work for others, but i have seen this combo stomp the guts out of some pretty expernsive engines.some rules say u cant use hump or vortech heads so this works out. the small 58cc chamber really bumps it up. good luck
