Hi guys, does anyone know if standard ('87 and below) small block head bolts
will work on a vortec head swap, or do I need to get special vortec head
bolts? Also, I am switching a tbi engine to carb and need a fuel pressure
regulator with a return port to tame the fuel pressure (12 psi) coming f

Thanks to everyone for the information.
I am sure I will have many more questions as I build this engine. I have
rebuilt hundreds of engines, but the last time I tried to BUILD an engine
was in '82. It seems that things have changed a lot since then (many, many,
many more options!)
Thanks agai
Mine is a 6 inch rod with KB hypereutectic pistone and
S/R torque big valve heads that were pocket ported. It
snaps when you punch it! This things I learned was to
buy the heads complete other than bare castings and
get a good machineist. Mine put it together with a
nitrided crank and the shortie p
I looked hard at a pair of L98 Vette heads for my car. However,they have
such small 58cc chambers that keeping the compression under control (and the
attendant detonation problems) as well as their angle-plugs sometimes
requiring new headers,sent me off in another direction. A good dual plane

Hi,
I have always heard that big valves really only help over 6000 RPM or so,
if this is a street engine and the old valves are still servicable I would
stick to them. Spend the money in other areas. A fast responding engine is
better on the street.
My 383 is running the early 90's vette alum
The cost to cut the seats for the larger valves probably isn't justified.
Stock Vortec heads flow pretty well but need the spring seats cut for larger
springs to handle lifts over .425. They also feature pressed-in studs and
will require a more expensive Vortec-compatible intake manifold.

Planning out the small block for my '68 Malibu. I want to build a 383, and
use Vortec heads. Everyone says that you can put 2.02 valves in these heads,
but I haven't been able to find any hard numbers on flow or HP gains. Any
ideas out there? Is it worth the time and money?

In the Jegs book, it says to use self

I have about the same combo 10.5:1 rpm intake 58 chamber heads 750 demon. You
should try the extreme 268H or the nitrous extreme 262H they both hit hard
and make about the
modifications such as umbrella seals that i could use so i could hold a more
mild cam than stock?
