afriend did the work for me...
local machine shop welded it all closed for us... i had flowed it before and after
and cant remeber the numbers for sure
its been about 4 -5 years ago
i dont have flow sheets anymore either...moved twice since then..

only real validation is i made 390 rwhp
at 6900-7k rpm(with 1" spacer) on Anderson ford chasi dyno
306 n/a 10:1compression all assecories on motor...
maybe not the best power out there...
but is definitely a sighn of good flow capabilities...

ttt...
answer on the spacer is yes i believe you can...but i never have tried it...i have 3"-4"cowl hood on the car with this set up

also to answer the heads question
they are old school twisted wedge aluminum heads
probably 170s......202 valve heads...
