Highest flowing sbm heads?

The set I have on now were ported over 10 years ago and are an old open chamber style. 5.97 so far with not as much as a jet change. That’s a 9.30 or possibly in the 9.20’s. My car is honestly not a go fast combo with a 14-32 slick and is set up for bracket racing not test n tune or I would 10 inch M/T radials on it. And hit a coastal track like many.

Absolutely not true. A full boogie W5 head can make a true 700 horsepower( based on both dyno and track results)
A ” chink” head can make 650 without moving the pushrod based on dyno and track results.

So, your saying my 100 hp estimate is wrong and it’s closer to 50 hp?

ET tells the story and I’m not the only one writing the book. Take those leaky azz W5 heads and plant tomatoes in them.

That be a possible future……

I can’t wait to but my new set on and then guys will really be eating their words. I’ve learned a lot in the past 10 years. Most of it coming in the last 8 months.

If such is the case. I look forward to being schooled.
