Using vortec heads on 350 come in here.

Hey i want to see your set ups with the vortec heads. I almost have everything together for my build using the vortecs going carbureted. Things i want to know are, what cam are you using. If you had the heads machined for instance the guides . What springs did you go with. I'm not sure how much o.d of a spring i can go with.

Chevy Hipo used these springs on there 350/330hp upgrade project. CCA-26918-16 valve springs, single beehive, 1.055 in. outside diameter, LT4 Hot cam and 1.6 RR produced 400hp on a dyno. I will post the article if I find it again.

EDIT: Sorry it was carcraft here is article. http://www.carcraft.com/projectbuild/116_0403_mail/
