Been looking and talking and contemplating New heads for a Magnum Based engine I want to build. I'm looking for a set of heads that will fill the bill but not be overkill or fall short either. Here's what I'm planning. 4.250stroke x 4.040 bore 7000rpm redline Pump Gas 10.5-11.5:1 compression Roller Cam Vehicle: 4000lbs 4.56gears 28" tires currently 3200 stall convertor Looking to build a HOT Street motor, Red Light Bruiser/Cruiser. IF it ever sees the track it would be every once in a while. The heads I have looked at so far are: Edelbrock Magnum Airwolf 220's Indy 360-1 What say YE!

Indy -1 is THE only way to go for serious power with that combo!

Brian can you share the flow numbers on those -1's? Did they start as 245's?
I can, but I won't have them until Wed. as we are closed mon. and tues.
They topped out at .750 lift at 360 something, and stayed there, did not lose flow after that up to 1".
At .500 I believe they were 316 or 318. I used a 2.125 x 5/16 intake valve, angle milled them down, our valve job, some short turn work, slight bowl work and chamber work.
This was a 245cnc intake port, but I did the ex. port and chamber myself. I don't like Indy's ex. port and chamber at all.

Only real problem with the W8-W9 is you really NEED a 48° block.
But I agree, W9 would be nice. I'm this close (thumb and forefinger almost touching) to having Sam at TTI do headers based on the W9 casting.
He's waiting for me to do an engine, supply the car and then mockup for it. This would be just like their LA and W2 headers, but 2" and 3.5" collector.
Once that happens, it'll be much cheaper and easier to do W9's in an A body!
KEEP US POSTED ON THIS!

I have W9's sitting on my shelf BUT the cost even cutting corners where I can it still adds up fast and exceeds what I could do with Indy.
As Brian said I would need to get a 48* block at $2200-2600 ad $2000 for machining that it will need. Ad $250-300 for AN Hoses and Fitting for cooling. $200-250 for an AN to Radiator Manifold, $1350 for T&D Rockers, $400-500 for an oil pan, $600-700 for Lifters, $500-800 for Lifter Bushings. ETC ETC!!!
When I have pretty much everything except the rotating assembly and heads. That's a lot of money I shouldn't have to be spending for what I want to do.
OH and the fact that the W8&9's have no place on them to mount Accessories of any kind. At least the Indy's come with LA mounting holes and the Magnum holes can be added (or even ordered from Indy) as needed.

I'm sure you're well aware of a stock blocks limitations. I'm not sure building a 435" engine with a stock block and -1 heads is the best idea ever.

Don't beat on it like a redheaded step child and it should last a while!!
As I stated in my first post this won't be a Race/Drag car!! Just a cruiser with some UMMPH!!
Plus I have an extra already on the floor of the garage and can pick them up all day long for $600 or less.

Going along with the previous comment, when you have killer heads and big cubes for a stock block, the best advise I can offer is to slightly under-cam the combo, you'll still have massively satisfying torque and power but by limiting the peak torque RPM you'll resist the temptation to over-rev it and beat the block to death.
Opinions vary, but that's the way I'd do it.

That's why I build them  Hope you can show more restraint than I would.
