its possible but not a good idea. the lifters work differently. u need solid lifters.

as for pushrod length. no one is gonna be able to give you the length. u need an adjustable pushrod. when you assemble everything, adjust the pushrod to the proper length. then that will be the length you need to order.

also be sure if you had a steel distributor gear originally(roller cam gear) that it will work with that cam. becuase i dont beleive it will. the steel gear is the hardest. which is equipted on roller cams only. so if your distributor gear is steel and you solid cam gear is not. the distributor will tear our cam up.

+++^^^. All I can add for sure is that the pushrods for a flat lifter is longer than the roller lifters. So def get your self an adjustable pushrod to check what you need there's plenty of how to's on YouTube to help with learning how to check pushrod length I'm doin same thing right now because I'm goin from stock heads to AFRs with crane 1.6 RR and pushrod length is gonna be different than stock. So gotta check length after putting heads on to order correct rods

No you cannot use roller lifters and pushrods on a flat tappet cam.
You will have to buy lifters made for the camshaft and size your pushrods as stated above.


IMO Return it and get a roller cam.
Why would you even want to use old school technology that will produce less power and add more friction losses to your valvetrain?
