Re: pushrod length
Unfortunately there could be a fair amount of variance that wouldn't allow a cut and dry answer. The stock length should work. The only way to be sure is to buy an adjustable length pushrod tool and check. With my Trick Flow heads the stock lengths worked but with my AFR heads I had to switch to a different length.

Re: pushrod length
If it's not all stock, then you've got to measure. Take a look at a short thread I had started when I was measuring for mine. There's good input in that thread on how to measure accurately.
