1G 1g head hp limit?

[Shtbox1gtalon22]

I’m new to this platform and I was wondering what hp rating are our 1g heads good for?

We have made nearly 1100whp on a stock 1G, unported casting. The car was out of turbo. Not cylinder head.

So stock valves ect.

I made 800 on stock valves, just upgraded springs/cams.

That car had basic stainless valves. My personal car made 800whp through a TH400.

That’s absolutely crazy I’m new to this shit and I’m doing a build rn so I’m trying to get the most cost effective build for 450hp that I can get

fuel, Link v3, SD, 3"exhaust and an FP red. Thats the "easier said than done" answer.
