340 Aluminum Head, Rocker Arm Upgrade

Powerflite said
I am about to install a port injection setup on the '72? 340 motor in my '67 Barracuda and would like to upgrade the headers, heads & rockers at the same time. I believe the motor is mostly stock, gauged just by it's power output.
1. Are there any aluminum heads that are clear winners over the others?

Yes, Trick Flow

2. Any idea how the 65 cc aluminum heads compare to stock heads from 1972 or 1973?

I have done a zero deck piston @ 10-1 - 360 w/J heads to Edelbrock heads and would call it equal to a set of ported J heads.

3. Would it be a good or bad idea to use 1.6 ratio rockers to increase the cam profile without touching it? If so, what rockers do you suggest?
Thanks in advance!

Yes and no. What you would have to consider is the cams profile as seen at the valve and consider it a different cam than if it was used with a 1.5 rocker. Small potatoes? Maybe.
Depends on how scientific your going to get on the engine.

From my “Hot Rod’ers” point of view, it’s a good move. I like to lift the valve as much as the head flows air.
From the scientist goggles, maybe not so much as the correct cam should be purchased if not a custom one.

PRW, Hughes Engines for 1.6 rockers.
I haven’t gotten to my Comp 1.6 rockers yet.
