Re: What's the value
$800.
Have the heads been drilled for accessories? If not, you'll have to drill them - they have no accessory bolt holes in the fronts for your p/s pump, alt, etc. (unless your using your 305 heads like we've been discussing - then you can sell those heads).
What's complete and ready to go mean? In my world, "ready to go" means I can start it and it runs on site - as in has an intake, carb, oil pan, water pump, starter, etc. all in place - but there's no mention of any of that - so you better get a definition of what "complete" means.
I say $800 because ... I paid $600 for my 350, and it was "complete" - carb to pan! Now, it's not pretty, it's old, it has smog heads - but it also has 10:1 dometop pistons, mild cam, and runs great. So, yeah ... I'm a tightwad! Guess maybe I've been spoiled by getting good deals in the past. Others might pay more than $800.
Good Luck!

You're buying a shortblock. Those 291 heads are worthless except to a collector. You can't drill the accessory holes because there's no pad on the end of the casting. The valves and seats are soft (unless replaced/reworked for unleaded gas).
No more than $500, depending upon condition.

Re: What's the value
OK - you got the expert answer from five7kid - he's da Man! 
The 305 heads would work fine with pump gas like we discussed before - might need mid-grade or premium to avoid spark knock, but at today's gas prices, another 10-20 cents isn't even noticed anymore..

He could probably unload them pretty easily to some old school guy stuck in his ways. Trending Topics

Re: What's the value
I was going to write something similar about these heads as maybe in the 70's they were the best, now they honestly suck compared to even late model factory offerings.
