OK gentlemen here what I am doing. 454 block .030 over. TRW forged pistions, L2349F I think was the # which is an LS6 duplicate I believe. To give you as much info as possible to help me choose I will be running a hydraulic cam, th400 trans with 2500-3000 converter, and approx a 3.37;1 rear. Choosing heads now:

I have 781 open chambers that came with block 118CC which will need all the work, valves etc.

I am looking at Edelbrocks 118 cc rectangular port performer RPM aluminum heads.

Also looking at Brodix Race ready aluminum 118cc oval ports with the 271cc runners.

All of these heads with 118-119cc should put me at about 9.5-9.75:1 compression so I can run on pump gas. Which do you recommend. Motor is going into a 66 Chevelle for mostly street but occasional track use and will be a weekend driver. My thoughts are stock heads are decent but the coin required to get them up to snuff will be quite large. The aluminums are kinda pricey but the extra weight and performace over the irons I figured was worth it. Now I think I like the Brodix the best with the small runners (271cc)and oval ports to keep the torque up. They have 2.25 intakes and 1.88 exhaust. They are like $1850. in Summit. The Edelbrocks are about $1750. in summit and have 315cc runners and are rectangular with 2.19 intakes and 1.88 exhaust valves. So what would you guys choose?

Then again World has a big block iron 118cc head for about 1500.

Opinions please!
