440 source heads

[Tom J]

Hello All! Wondering what yall's thoughts are on the 440 Source stealth (single spring) heads are? Thinking of getting a set for a low compression 440. Looking to also replace cam...ideas? Have a performer RPM intake on motor now.
Looking for set up suggestions ETC.. Car has 727 stock converter and 8 3/4 sure grip with 3.73 gears.
Thanks for help in advance!

What year 440, 1967? If so I wouldn’t bother switching cylinder heads. As fat as camshaft I would contact a grinder like Jones Cams and ask for a custom grind.

Best Mopar wedge performance heads on a budget...

Just my $0.02..

I had Dwayne (PRHeads) brush up a set that I'm going to put on a 72 440 with a comp 501/510 solid and a gear vendor OD and 4.10's. I expect it'll run ok.

I got the dual spring heads on a bored 383, less expensive than rebuilding the 915s I was going to use, lighter, iirc flow better.

I ran it with an RPM intake for a bit, no complaints.

Decent upgrade I think. And man that's a great looking 66!

What did you end up doing? Anyone know if I would be around the same money reworking a set of 915 heads?

Yes. There's many different operations to rebuilding a stock pair of heads. Seats. Guides. Valves. Springs. Retainers keepers. Milling. Cleaning. Crack checking.
It all adds up fast

Add to the variables……. What the auto machine shop labor costs in your area are.

At my shop it’s not hard for the price of reworking factory BBM heads to exceed the cost of a pair of Stealths.

Used to be stock ones called Aeroheads that Indy sold that were set up with bigger valves and hard seats. Seems like they were like 600 bucks a pair and you could pick the casting number for 100 more. Not sure they did 915s. I haven’t seen a price sheet for several years though. Seems that ended with Covid.
