Re: [Amc-list] 304 head swap

[Greg Taylor <amundaza@xxxxxxxxx>]

Hey guys,
Thanks for the real-world feedback.  I’ll sell the 291C heads and invest the $$$ into the good 304 heads … have a pair of 1970 304 heads in waiting … just wanted to make sure about the big-valve heads, first.  The 304 heads will get 1.94/1.50 SB Chevy stainless steel valves with undercut stems for low-end torque & mid-range increased flow.
 
The 291C heads were ported for a full race 360 engine that was running in low 11’s.  When I get them back from the machinist, I have a few people interested in them.

Sincerely, 
Greg Taylor :) <><

Bruce is right on the money on this.
I've seen the results of big valves in small motors. I knocks the crap out
of your bottom end.
I doubt they are what you want in a torque motor for a Fullsize 80's Grand
Cherokee.
   You might wan to consider finding the good 304 heads and have them worked
with small valves and stems etc; It would keep the velocity up and help torque.

I don't remember what you said the heads were originally ported for, but
seats and smaller valves may not be enough to do the trick.
