What's your opinion of the 305 Vortec Heads? I"ve got a 305 in my 84 Trans Am and I'm trying to decide if I just want to swap it out for a 350 that I've been wanting to build for a while now, or just upgrade some of the parts on the 305. I'm wondering if the 305 Vortec Heads are any good of if you all would have something else to reccommend? Additionally, I'm looking at these headers...
Edelbrock TES headers
Obviously, the vortec heads would require a new intake but that's something I'll have to come to. With the heads and exauhst I can expect what...about 60hp gain or so? I guess it comes down to money. For about $1000 I can spruce up the 305 or 2500 I can build the 350.
