I am assuming it is possible to safely remove enough material from the heads that the lifters can be removed with the heads on? I am running comp 828-16s.

I am changing my roller lifters out before drag week this year so I will have the heads off and would like to modify them if possible. It would be super awesome if I could do it with them on the car, but I am sure its not that easy!

Thanks
