stock heads hp

[HURRICANE HAVOK]

do anybody know how much hp can a stock head hold with a big turbo

 

[greenhaze77]

I would say at least 500 HP. The engines in general are built pretty well.

Head or head bolts? What's your idea of a big turbo? What rev range? Man, there's a billion different variables here.

 

[HURRICANE HAVOK]

i have 272 cams and a 25g turbo.

Is it a health engine no exact number how much boost a lot of variables to be determined here, if in doubt I would replace them with arps just a idea.

Well the head on a 6 bolt has huge intake ports, but not the greatest port entry angle. The 2g head (not necessarily a 7 bolt) is regarded as a superior design, and can be ported to flow enough for over 1000+ hp. In fact both heads with some work, will def be able to support pretty much any power level you can make. Matter of fact the head its going to be one of the last things you "need" to address. But of course the more efficient, the easier you'll make the power your looking for. Always keep the ports as small as possible, just enough to flow what you need, but also keep velocity high enough to overcome reversion and have good throttle response.
