Speedmaster rockers
Absolutely right!!
I have seen guys stamp the number on the rod and
have it stress crack and break from that spot in 10 passes
or less.
Forget about the rockers = On my street 10 sec. valiant
with just 140 Lbs on the seat they broke a 1/2 Dozen @ 1000 Ft mark (5500 RPM)
Pins and rollers f flying everywhere and two adjusters flying off like a rocket!!!!
I like Brandon BUT He would not Warranty them = He said "John they are 6 Months old! Yes they were but I order everything well in advance when building an engine NOT the week I build it and find out I can not get the parts for months!!
One of my friend bought a set of his heads some years back and spent a ton of money
porting and preparing them ONLY to have the Valve springs break thru the Headin the seat area when setting
them up (Never even got it built and running) and again with only 140 Lbs on the seat and
never even got a rocker on the spring to open the valve. I felt terrible because I had picked then
up at Brandon's place for him and was kind of in the middle. Brandon said he had a bad batch
come thru with the same problem and it would be 6 months before he could replace them with
another set. Plus my friend was out well over $1000.00 for prep work and porting.
I am sure these problems are the exception to the rule and he is a nice guy I have known
for a ling time ---- But I am DONE!!
If money is tight = I recommend the Edelbrock Heads.
I watched my friend "Bob Mazzolini" run in the 9's @ 130+
At MATS last weekend with a mild budget 432 (383 Stroker) in his Beautiful 68 Valiant
with these heads on it (The cheaper E version) and I would
guess it weighed 3400Lbs with him in it!!
This was @ 3200= FT. mean Adj Altitude with a Headwind!!
