5.3L pushrod length on milled Just wondering what the pushrod length when using a 5.3L heads milled .010. Car has a stock bottom , cam specs are 224*-224*-110*-.635"-.610"
, head gaskets also not sure on .040 or .045. Have a set of 7.40's but wondering if i need to swap otu for 7.349's or what

Measuring is the only way to know for sure, but I would think 7.400 is about right for your setup.
I have 5.3 heads that have been milled .025", with .040" head gaskets, and am using 7.375" pushrods, but I suspect they might be slightly short, as it makes a bit more noise than when I was cam-only with 7.425".
I have a set of Yella Terra rockers to install, and depending how much I need to shim them (which will also alter PR length), I will then measure and order the correct length.
