Home ported D0OE 351W head flow numbers

I picked up my heads today and got the results of the flow tests. I spent waaaay too many hours porting these suckers, but it was a learning experience and generally therapeutic. The valves are 1.90"/1.60".

Here's what a moron with a grinder can accomplish, tested @ 28" H2O:

Intake:
Lift - Stock/Ported
.10 - 58.7 / 63
.20 - 105.6 / 116
.30 - 152 / 169
.40 - 171 / 199
.50 - 181 / 211
.60 - 189 / 211

Exhaust
.10 - 51.8 / 51
.20 - 90.4 / 97
.30 - 106.8 / 122
.40 - 112.9 / 134
.50 - 114.8 / 143
.60 - 115.4 / 146

FWIW, not too bad for an amateur and better than what I had.

Good Results !! Great project to learn on too !!

Your that much closer and that much more power now

Nice work...Did you take any pictures?

Here's a few pics after and a before. There's a lot of metal in that freakin' hump. I smoothed out the chambers quite a bit as well. Tons of fun!

How many hours do think you have in them?

The numbers look real impressive there better than the first set of world products heads i bought . Like you said if you incloded the hours the price would pritty high . You did a grate job good work.

Somewhere between 20-30 hours I'd wager. It was on-again/off-again so I can't say for sure. Between them and other projects it dragged out over the course of a month.

The first 50% of the first head I ported was slow as heck - then I got a set of carbide burrs at Sears. The burrs knock down the big stuff so much faster (and more accurately) than a stone or cartridge roll.

I almost bought a set of used World Jr heads for $400. With the valves and all I've got about that much in these. And I did it myself. They'll be great in my old Bronco.
