Need specs on SB Chevy Cylinder Heads...

[Mark B]

Hey guys,
I will be looking for a set of heads for a 400ci Chevy motor soon. I need to find out cumbustion chamber size, valve size, etc for particular casting #'s. If anyone one knows of a link to a good website with this kinda info, I would greatly appreciate it if you would foward it to me.

If youre on a budget, you might try a set of 72 CC iron eagles- theyre like $350 ea and probably would give you around 9-10:1 compression. More than likely they will outflow stock irons.

Where can I find them?

Any speed shop can order you up a pair- Jegs has them too I think. If you need more compression, then 64 cc chambers are available, but I'm not sure how much compression this will give you. Before you buy them check with a service rep as to exactly how much compression in a 400 you can expect. Or maybe Injuneer could answer this.
