The way I see it and I am no professional.
Get those w2 heads.
1)most people buy new rockers so what's the difference?
2) stock headers bolt up to w2 heads. May not flow as much but they do work (dual flange)
3) intake. Yes they are limited for w2s but if your hunting for an airgap or single plane. The price is near the same for w2 singles.
Now we have that out of the way.
I started with a stock built 340 that came with my dart. (Unknown build)
It lasted a month till I spun a rod bearing.
She loved to rev and spin tires.
I debated 440 bb build as I had a 440 in storage, but I had all the parts for a small block build. So I chose sb.
Stumbled on to a set of w2 heads....
Next I built that 340 block to a 418 w2 headed monster. With the single plane intake it felt like the car was lazy off the line.
So i Swapped to a w2 dual plane and it was OH MY SHORTS... I felt like I swallowed my face and sucked it out of my ***.
Now the 418 w2 monster never sealed right and would burn oil. Could not fix it after 3 attempts.
So back to the drawing board.
New machine shop.
New 340 block using my stroker rotating assembly for 418
New indy 360-1 heads that I was not planning to get but I got an awesome deal. So i dragged them home and had them pro ported.
We will be testing this summer if they SPIT my face out of my rear.
