I've been browsin for heads for my LT1 , i notice there isn't that large of a selection.. Any recommendations to get the most power out of the lt1 with a cc306 cam.. what heads would be best, and what work should be done to them.

 

id' ask on a 4th gen forum....

try camaroz28.com
lt1forum.com etc etc

 

If you've got the money, AFR LT4 heads are the way to go. You'll be able to get outstanding power with those heads and cam. If money is tight, get ported stock castings. They will flow great and still let you get good power. My friend is using stock ported heads with a 306 and pcmforless tune. He's still putting it all together so we'll wait and see what kind of power he puts down.

 

I agree. The stock heads can go pretty far with some good port work and bigger valves. If you don't have the money for the AFR's you could always look at the new LT1 heads that edelbrock has out. It has your standard performance valve size (1.94 and 1.55) but should be much better than stock. You are looking to spend about 1000 to 1500 for new heads or a professional port job on your current ones.

 

Didn't know they did, I'll have to check those out.

 

yea they are brand new. They are in the jegs cataloge now but before that I just saw their fill in adds in various chevy mags. I also hear that Trick Flow has a wicked head but I do not know anything about them.

 

I looked at the Edelbrock's last night, don't seem to shabby. 73 hp with those heads and their cam isn't too bad at all. I wonder what those heads would do with a different cam and some porting. I looked at Trick Flow but couldn't find any LT1 heads. Although I did like their 18* heads

 

I just wished those Edelbrock heads had bigger valves. I wouldn't use their cam either. It is probably okay but there are so many proven great ones out there. But 73hp does soound nice, but 150 sounds better.
