I picked up a set of '77 810 casting w2 econo's last year. Heads, rocker set, intake. A few of the rockers need reconditioned. I think these are long valve versions econo's. I took a pair of valves out and they were longer than stock 340. Had I known this, I probably would have passed on them. My understanding now, is that they made long and short valve versions of both econo's and race heads.
Well, just for a street motor. Was thinking of selling them. Manly SS valves, big block sized springs, etc. I picked up a set of fresh x heads and 340, so probably won't need them.
I ran W2 heads for years in three different S/B combos with the ductile iron rockers and never had a single problem replaced one adjuster screw in over twenty years. I got them when I bought a complete 627 lift roller cammed, 12 1/2 to 1 comp. 340 for $2500 many years ago. I went a best of 10.40 with them in my last combo 30 over 360 crate short block, 590 lift but mech.cam, 11 1/2 to 1 comp. we always knew it would run low 10s with a roller cam but I never did as I slowed the car for a different class. I still have the motor still ran great with still good oil pressure and valve springs since I went to my 408 I m debating what to do with it.A few more pages
