What do you guys think of the speedmaster bare aluminum heads

why 5 why not 7 including bottom cut to start to address #3
margins and back cuts are important
radius on the ex valve?
valves- flat or dished
"pro flo" or other small stem valves
Magnum valves?
Lots of LS valves in the correct or longer lengths in addition the the usual SBC
bead or square keepers
10 degree?
plan ahead
Why?
How many cylinder head machinists where he is do 7 angle valve jobs?

How much does that run?

I have been completely ripped off by two machinists that could do the work, and the fair machinists that I finally found that were reasonable only did 3 angle valve jobs. There are THOUSANDS OF REASONS NOT TO.

Not everybody is floating large bank rolls nor competing with the 700X more popular LS or SBC competitive aftermarket.

Why didn’t you run twin turbos?
At the back of the car like calloway corvettes?
Why aren’t you running a 3rd gen Hemi?
A tunnel ram? 4.30 gears? Dana?
Why aren’t you running trick flow heads?
Hint hint
Why stop at W2’s, just get the w9’s and a Ritter block!
Why don’t you run the LSX 454 setup?
Have you considered nitro methane?

That camshaft is not max performance, you are leaving horsepower on the table.<-Your most recent posts.


I do appreciate your insight Wyrmrider, and some of your wisdom, but how about you simply provide a comparison example WITH the estimated loss of performance left on the table and a comparison of cost analysis if you think the guy buying Chinese cylinder heads is walking away from major performance gains?
