318 piston's and quench

"Well, I'll put it to you like this. If you already HAVE open chamber heads, it ain't worth the extra 3-6% difference in power to g through all the trouble to find some good close chamber heads."
All depends on the individual post. I read Dans post as he had an engine with pistons and a set of 302 heads. My mistake I realized only after Dan said he didn;t have an engine yet. In regard to your numbers - I don't build quench in just for power. I build it in for that additional power on cheaper fuel. While it's hard to justify 10-15hp on a 350hp engine, 10-15hp while being able to run fuel that's $.50 a gallon cheaper, and getting an extra couple mpgs is pretty easy math.


"It sure is funny, whenever I recommend the 302 heads, you're one of the naysayers right there on the spot trashin them but whenever they strengthen your argument, hey are the cat's meow."
Every situation is different, but 302s are rarely anything I'd recommend - unless someone has them already and they're confirmed usable "as is" or already re-done. Aquiring a set, having them inspected, and having the repair work done will cost more than aquiring stock Magnums, or EQ heads that can be had for the same money or less, and will give better performance in adddition to the closed chambers. Sometimes you get something right :D...(IMO of course...lol)
