Greeting Ford Six Fans:
My 250 block was decked .030 to achieve near zero deck height, and I am using a composite head gasket, which varies from the compressed thickness of the original steel shim gasket. As noted elsewhere, am using the CI aluminum head, which I have been told has the same external dimensions and rocker arm geometry as a stock head.
While this is a straightforward concept - use the adjustable pushrod from CI to measure the correct pushrod length, then order the pushrods from CI - there are a lot of variables here:
I'm using 1.6:1 stamped steel adjustable rocker arms
Soaked the hydraulic lifters in break-in oil and pumped them up about 30 times each with a pushrod, but it's hard to say exactly how pumped up they are compared to normal operation
The measuring pushrod itself is adjustable
With all of these variables, how would you approach this measurement?
Thanks
