I am about to do a cam swap on my truck, (03 lq4 aluminum 317 heads) and I bought 3/8 diameter pushrods but today I was told they might not clear the hole in the head. anyone have any input on this.. if they don't this might be a sign to pull heads get the P&P and decked with new lifters
but on the serious note would they clear the holes in the head?
Thanks in advance!!

 

bump.

 

Not sure what the sizes are but SDPC would know , they have always been helpful and sold me the correct parts .

 

will be giving them a call tomorrow, thanks!

 

For anyone curious, 3/8 pushrods would fit trough 317 heads just the clearance is very small so you would have to bore the hole out to be safe.
