I've been looking in to getting some heads for my 351w in the next year and noticed most used heads say setup for Roller which my 70 block is not what would need to be changed on the heads to run on non roller block
thanks

I believe just the springs need to be changed for a non roller cam

I believe you need flat tappet lifters also don't think roller lifters will work with that cam

Thanks for the responses. will look in to what springs are currently on the stock heads(car in storage)
And the cam is a flat tappet Edelbrock cam not sure which one probably the performer cam,
Where on the cam would the specs/Part# be?

The numbers would be on the cam it's self. An get new springs that are correct for the heads. An any good machine shop can measure your old springs an tell what the pressure they are.
