What size valve springs are on the heads :?: Also they probably came with .100 long valves so you may need .200 lg push rods. You'll $'s ahead if you just buy an adjustable pushrod for $15.00 and do the measurement, all cam company's sell them and so does Manton.

Thanks, i'm going to run it this weekend. .200 may work, but if they don't you're out $80.00 to $100.00, it's just a better investment to buy the adjustable push rod., and then you'll know for sure what length you need.
