Howdy,
I have a 1972 400 with 213 heads. I want the heads for another project, but I still want to drive my satellite with the 400 in it in the meantime. I have a set of 516 heads that need a rebuild.
Will the 516 heads go on without any problems? It's going from open to closed chamber with an already low cr. Will I actually gain any power? Or would that only come with bigger exhaust valve and some porting? Im not looking to gain power necessarily, but I'd rather gain than lose. It's not for racing and I know they aren't hardened seats.
Engine has a Holley dominator intake, 750 cfm carb and 1 3/4 hedmen headers if that makes a difference.
Thanks
