Iron or aluminum heads?
#25
Don't forget to reinforce the passenger side floor board so it doesn't fall out and oh be careful with the welds on the intake manifold.....and then you should be good...
Why stop at a little 300 shot...i would go with a 2 stage 400 just add some octane booster from the local parts store....

The other benefit to the iron heads over aluminum is they make a little more power at the same compression ratio. The iron doesn't dissipate heat like aluminum, so it keeps more heat in the chamber, thus making slightly more power. In my opinion, I wouldn't take the small power advantage of iron over the weight advantage of aluminum, especially over the nose of the car.

i know this sounds like a dumb question but.
i wanna know what would be the best choice to go with on my lt1
I have a stock bottom end lt1 with 100+K miles on it and i need to put heads on it. i am gonna put a 300 shot of gas on.
Now i wanna know which heads would be better to run on this. the iron heads? or the aluminum heads?

yea like maybe not even to the end of the track ......
dammnnnnnnnnn...........now i see your reason for the 300 lol....just remember if it pops before the end of the track you still loose lol
yep lol.....
i like the th350 idea now ur thinking but idk about that shot the 200 you may get away with for a few passes but that bottom end sounds like its a used old lady with over 100K on the clock.......id be careful

The engine doesnt run on 'flow,' run the aluminum head. We have dozens of 1XXk mile heads/cam customers in the 380-420rwhp NA range still running without issues. The mileage isn't a problem unless you already have issues that need to be addressed, and the short blocks are more robust than people give them credit for. However, you will eventually lose a piston if you are actually trying to get into the 750-800hp range with it. Keep in mind, you should be able to manage 7.20's w/ 50-100hp worth of n2o in a well setup heads/cam car. At that level, it should last awhile.
