p51 heads

i have a few questions about the p51 heas. in the process of swapping a set of A429cj heads off for a set of p51. my question is as i was being told i cannot use my pushrods that i have now. whats the length and does anyone has a price? kaase doesnt list the price on them? if the pushrods are .100 longer then factory can i use the ones i have or will i need them longer then what i have?

The rods are not only longer but, the exhaust are longer than the intake.

You'll need a new set of rods. I get about $125 for the 3/8".

is that something you keep in stock?

You best to check for proper length before you order. There are some slight variances in the rockers from manufacturer to manufacturer that will affect pushrod length.

For example I went from a set of the FRPP A460 blue rockers to a set of the new Comp Ultra Pro Magnum and I need a slightly different length now.
