Iron vs. Aluminum Cylinder Heads

Enjoyed your discussion.. Reminds me of the days when I had a 68 Dart GT with a built 340.. Built by BO-LAWS of Orlando Fla around 1970.. He dynoed it at 425 h.p. It had cast iron heads and lots of the old school stuff.. Ran 12.5 c.r... 4:56 gears.. lots of fun.. same color as the Barracuda in your shop ... I hope to see more videos of your Barracuda.. Gorgeous car...

It's so true about SBC....I got a pair of assembled aluminum heads for $200 less than it would've cost to rebuild some Vortec heads.

As long as you save the original parts, it doesn't matter, just screw it back in if you want it to be strictly original again.

Great explanation. Those who pay others, often arent driven by what costs less. Their "budget" includes labor paid to "shops". The guy in his own garage often makes sense of his decisions over fifty bucks difference. Iron heads or no heads, brother! Love your channel, subscribed!

On a 440 Mopar you can get 521 horsepower, in a streetable build using cast iron 906 heads with oversized valves and porting using Mopar Performance porting templates. That’s good for 10.80’s in a light ABody duster when everything is done right.that includes using a windage tray and blocking off the exhaust crossovers.

Finally ! a forthright knowledgeable discussion of the considerations all things cylinder head when restoring. I'm a Full Service Machine Shop, and if you don't mind ? I'm gonna copy/paste and link this to my customers to save repititous explanations Iron Vrs Aluminum. I mean we'll still do light/cleanup style Bowl work on the Iron Heads ? but really.... guys just don't 'get' the time($$) consuming extra effort with cast iron Vrs the Flow gains of Aluminum for $$ spent going Aluminum on whatever target application. About the only thing I can add might be the old 'rule of thumb' for Heads.... that being to divide whatever "HP" target is being considered and divide by 2 = Target Head CFM @ whatever Cam lift ? Obviously LOTS more involved ie: Dynamic CR/Type of Cam(F.T. Hyd vrs Mech Roller etc).... but for the most part it's a quick incipient head target ? 500 hp/2= 250 cfm @ lift. THX for sharing.... my Flow Bench Thx you... I THANK you !

Blake who did your back trim and your front trim in argent silver???? On your red cuda I would honestly leave the roll bar in Alot less mess just paint it looks nice nothing wrong with the bar I would leave it alone!!!!!

Ethanol indeed has its problems but Ethanol raises octane!

Uhm?? FE cylinder heads are not a big head? Becouse part of the head is cut off. It's part of the intake? U have said a few key things that make me question ur knowledge??
