This may be a basic question, but with my luck, I though it would be best to ask the experts before doing the modification I have in mind.

There it goes:

I rebuilt my 292 Y back in '09, and I installed a Isky E-4 cam. Like the stock rocker arm assemblies were great, I decided to keep the original rockers (5751066, that have 1,43 ratio) on.

My engine also has a set of Clevite Pistons, flat top, 0.040 over, flush with the deck.

I was given by a friend two complete rocker arm assemblies, rebuilt by 4 Star engines in Kansas, that are like new. The ratio is 1,5

Can this swap cause any problem to my engine? Basic question I know, but it's better to be safe tha sorry.



Thanks for your time guys.
