Hi all,

Does anyone know the maximum valve lift and installed spring height on Indy 440 EZ-1 heads?

Indy are being their usual helpful customer service!!

Thanks

you asked twice so I asked the internet

EZ head Same as stock according to Mr hughes

EZ-1

The 440 EZ-1 is the same cast head as the 440 EZ with the intake openings CNC machined to the Max Wedge size and CNC bowls. This allows all Indy manifolds to be used or all after market Max Wedge X-rams. Both EX and EZ-1 use standard Chrysler rocker shaft oiling. Standard low exhaust port.

so in my book exactly the same as a stock 440 head

dunno what that is though

Thanks Dave,

Didn't mean to ask twice
I asked the internet and got the same answer as you did but not the max valve lift or installed spring height, or did I miss that on the link?

no I assumed that for a standard/stock head it would be plastered left right and centre all over forZbodies only and allpar

must be in the books somewhere

you going for mental cam? offset retainers?? more spring,less bind,same valves, Bananarama! reatiners etc oh just a little notch will be fine honest etc etc

I know nout about V8s let alone those that use fancy aftermarket heads

hence I approached cautiously

Just weighing up our options.

Need as much info as we can get so our cam grinder can see what he can make for us
