What were known as our "Big Valve Heads" have been replaced
with the "Premium Big Valve Heads" line since we stopped using the REV valves
about 4 months ago. The new Premium Big Valve Heads have the Manley valves with
the pro flow shape. Sizes are 2.10"/1.625 for the 6.1 and 2.02/1.575 for the 5.7
head.
The new Manley valves will be running single groove locks with high quality
Crower keepers and retainers which blow everything else we've seen away in
quality. Essentially, the Premium Big Valve Heads are the best quality
components that we can source with the Manley valves and Crower locks and
retainers.
If the intended valve lifts are under 0.580/0.566" exhaust
for the 6.1 heads and 0.566/0.566" for the 5.7 heads the OEM 6.1 springs are the
best option, as they have sufficient rate for the fast ramp cams that are out
and are the most reliable springs available. (if it's not broke don't fix
it!) For higher lifts contact us for the various options in valve springs,
locators, seals.
