Does anyone have experience with the Speedmaster aluminum heads? They had a great sale last Christmas. Didnt know if anyone has run them. If so, what are your thoughts vs 440Source, Eddy, etc
The ones I've seen are about small block heads that's why I'm interested to see what big block guys have to say about them. Also I thought there was a couple different kinds? Of big block....There's a sticky thread that might answer most of your questions.
We may use them on our 440. But, I have to be honest...... looking real hard at the Edelbrock, and even considering building the cast iron heads. We are looking to build around 475-500 hp, but gobs of torque and street manners. Not sure these SM heads I have are the right ones for our particular build. May sell them and dump the money into another set. Shhhhh.... even looking at E-streets. Seems they are a fantastic street heads and some great reviews and numbers being posted with these heads in heavy street vehicles.@318willrun has a set. Maybe a inspection and comparison thread + video? BB vs SB?
I’d look at the sidewinder heads from Marsh Performance. Heard a lot of good things and for the price, it’s worth itDoes anyone have experience with the Speedmaster aluminum heads?

wow, I just visited their site. Really priced right and flow numbers look decent OOTBI’d look at the sidewinder heads from Marsh Performance. Heard a lot of good things and for the price, it’s worth it
Yeah, I was gonna run them before getting the sweet deal on the RPMs I ended up going with. Marsh will built them with your specs and with parts from Isky or comp or whoever you wantwow, I just visited their site. Really priced right and flow numbers look decent OOTB
Does Speedmaster sell both styles? And as one style require different rocker gear than Factory?...There are two different BB Mopar heads from SM.
One is the copy of an RPM head(and is the same casting as the Sidewinder head), and the other is a copy of the first gen of the Victor head.
The RPM copy head from SM seems like it was rarely available through them much in the last year or so.
The Ede, Stealth, SM heads all have their pluses and minuses.
I'll have to mark my calendar an actual experience review instead of just heckling.......I think the 440 source stealth head is the best bang for the buck.
The set I bought needed minimum cleanup and perform well.
Small block or big block? I would imagine big block. Does 440 Source even make small block heads?Does anyone have experience with the Speedmaster aluminum heads? They had a great sale last Christmas. Didnt know if anyone has run them. If so, what are your thoughts vs 440Source, Eddy, etc
I went out on a limb because it's the big block section...Small block or big block? I would imagine big block. Does 440 Source even make small block heads?
I made my choice based on a thread Jim Laroy has on them.I'll have to mark my calendar an actual experience review instead of just heckling.......
