Who makes thicker walled pushrods?
talked to FTI, they can get me a 5/16th OD pushrod with walls up to ~.113 thick. above that you have to go to a 7/16th and that may not work with the stock pushrod holes in the head.

But I believe you'll have to play close attention with a ls1/ls6 head in regards to increased o.d. diameter pushrods.
I actually need 7.225" so I'm limited there too.
yes, it will make the oil passage smaller.
