head bolt bulge in runner?

Marland,
Also keep in mind that your engine is only 282 or so CI's and really cant use more than what head that you have, If your looking for engine HP then 364 HP is what you have. 1.29 HP per CI is very good for the cam that your using, and making up to 1.5 HP per CI is fairly easy but after this becomes very expensive.

The 322 at 1.5 HP per CI would be 483 HP and this is a 318, so 423 HP from a 282 CI engine is strong, so 59 more HP is waiting for you in machining of the short block. For instance a 408 that makes 500 HP from the engine is only at 1.23 HP per CI and one that makes 550 HP is 1.35 HP per CI.
The 322 is at 1.38 HP per CI or 443 HP with a .528 cam and ported 302 heads, KB 167 pistons and light weight parts, and this is detuned.
