1975 head and block, had a ton of work done to the head so lift is now .531 (for the clifford cam).

will regular length pushrods now be worthless?

is chrome moly worth it?

How much have you shaved off the deck or head? That determines if you need shorter PRs. Cam has only a small effect.

Stock Pus Rods will work there. I had to go to shorter ones when I had taken 100 of the head and block.

so, a .010 difference from .090 made you have to shorten the rods? that makes me think I might need to get shorter ones now.......

how much shorter than stock did you go?

or did you mean .100 off of the head AND the block (as in each instead of grand total)? I am not sure what you mean.

Actually you need to wait until you have the head and block assembled to see where your rocker arms hit the valve stem tips. Before that time, anything is just a guess. :shock:

I would say a rule of thumb is that anything up to about 0.080" shave and you're safe, BUT I agree with Dennis that you really need to measure to get it right.

You still might be OK.....also depends on the base circle of your camshaft.
I would do a mock-up and see where you're at. Also if you have installed valve spring with more spring pressure you might want to think about after market push rods. I found out the hard way.

I never got shorter push rods. I have 0.100" of the head and a mild cam. there is still plenty of room for adjustments to the rockers.

I was planning to use the clifford rods, is chrome moly worth the extra cash?

the head work was designed to fit the clifford cam of .531 lift.

I would say you "need" thicker pushrods, (and maybe shorter...)
They are awfully long and thin...
Just if the stock ones are too long :wink:
