The resistor plugs made no difference in
our testing. In our MSD 6 Street/Strip cars
we run .040 with a plug with that ground strap.
We did not find any power in those car from a
wider gap and I believe it puts more strain on
the rest of the ignition system.

We took it back to US Nationals (Indy) and beat all the
Mustang GT 302s/Z28 Camaros/400 Pontiacs to win
N/SA class. Jon also got to the Semifinals a got beat
by some guy named Biondo in eliminations.
We really enjoyed meeting a lot of people we had only
talked to before. It was also rewarding...
Does the adjuster not have a recessed area on it
to align with the oil hole on the rocker on your adjusters?
In the old days, Mopar Performance recommend .250
to .280 protruding from the bottom of the rocker.
60+ Years ago, I thought it was really not important and
I burned up the Valvetrain...
The best Dyno HP for a production header was
hands down the 13/4 5204 Hooker. Do they hang lower
yes somewhat but we run them on 360 68 Valiant
that runs on the street and still runs 10s when required.
There have been several postings on it in racers section.
I always have a few sets of these...
I have had a show winning 71 Hemi Cuda
and a 1 of 2 (Per Galen's Report) 71 Challenger
340 4 Spd. Formal Hardtop 20,000 immaculate survivor.
I would never take either one out of the shop and uncover
it, except for a show or when I sold them. Sold the Challenger
to a Major Collector in Phoenix...
Ya know, It probable did not make any difference to most buyers, but
there was $16,000 plus in the engine and transmission in the
Duster (Not count any labor) and it was very streetable and ran
11s at our altitude and heat the way my boy's Father in Law drove
it on Weekends.
My solution to the camshaft disaster the last few years is
to buy and accumulate all the good CWC old school cores
that have a generous amount of extra meat left on the lobe
an no damage.
I then can get them reground to whatever profile I want by
a company such as Clay Smith or Oregon. Every...
I have known Brian forever and never heard a bad word about
his work or integrity. It is well worth the freight and the wait.
My Dad told me = You buy the Best, You only cry Once!
George who has owned the shop since I wore short pants, is well up in his 80's
and his son in law Chad has had a transplant and not a young guy either.
They have plenty of work. Back in the 60's/70's, George built some of the fastest
Max Wedge Cars in the country (Including helping with my 64...
Respectfully, i suggest that forum guys take a look at both
vehicles and decide for themselves the work quality and detail
of the cars.
Neither one is a 340 H code car, let alone matching number
restoration high dollar piece. Our car was only an original 318 G
and no 340 but only one repaint...
There is only 3 CCs difference between the two part
number heads and sometimes different castings CC
a couple CC different than another pair the same number.
In our testing at low 300 to 400 lift the 675 flowed better.
Plus, I prefer the open chamber heads myself as they seem
to have less...
