Any early A fans that can fab headers?

A standard un ported (just a decent VJ, bowl blending and guide shaping) W2 port on a 340 motor starts pulling really nice at just below 4000 and pulls hard through about 6800. This is a 440 inch small block so proportionally the sweet spot will start coming on as low as 3200 and pull really well into the mid 5000's, the heads are ported to allow the motor to rev and not drop torque rapidly above the HP peak.

We just did a very similar design philosophy for my buddy's 442" AMC with similar size ports and a similar hydraulic (this is a solid but compensated for lash) roller and it made 545/545 with a torque curve as broad and flat as Nebraska. Ran 12.90's at 103 in a nearly 3800 lb w/driver jeep granny shifting at only 4800 rpm. (First pass down a drag strip, when he shifts at 6000 I promise it'll go at least a 12.20.

Headers are important but not as critical as many people think when the combination is well sorted. W2 doesn't need a lot of overlap (fifth cycle scavenging) to keep the holes fed. spitfires were far from ideal but I know they would at least fit. It's no matter now since Stephen Daurity is going to build a proper set. This is just gonna be a driver do I'm not too worried about over 5000 rpm

I didn't want to leave much on the table but I was willing to only because I had the motor before I found the car, fortunately I hadn't speced a cam yet.

With respect, y'all.....I've got a 'pretty fair' level of experience with strokers guys,
Been building them for close to 30 years and can predict within about 5 hp what a motor will make. I've got a 517 low deck bbm, a 427" sbf and a 414" SBM in the garage right now. Check out wizerulz on YouTube.
