Do you have any history on tests of the 034 cast BowTie Heads? I ask this here because I think both the 034 and the 292 Turbo were similar. Am I wrong?
Ed, i have also a bunch of Flow Data over the years on
the #034's Heads.
There are at least 4or 5 versions of these cast iron 034's in
the years they made them.
the first version is not enlarged outward on exhaust side of casting,
so it looks similar to old 292's or SBC heads except for small exh ports
the second version Chevy enlarged the water jacket side on exhaust/
sparl plug outside..so it has a very noticeable exterior , with more metal
around combustion chamber
the 3rd or 4th version was about the same,
but had a dip in intake flange casting where heat-riser was located
The #034 had a higher Ski-Jump Short Turn
with no water above intake ports + smaller CSA exh ports
i have 2 Band-sawed (1)034 and (2)292 heads i could Post pics of
Ed if you asked me that same question about 10 years ago,
i'd now exactly all the specifics
i ported a pair of #034's for Benoit's C/ED in 1980's,
according to 3-4 page article in National Dragster "Bayou Bullet"
it was the first C/ED to run in 7 second ET
set Record C/ED at 7.97 ET ??
he later ran 7.80's but not a Points Meet where the record could have
been reset..later switched over to B/ED with Pontiac-Brodix 23deg
raised runner heads 337CID or 338 CID ??
