Will this bore clean up, magnum head content too.

Sheeeyit. Heard from bullet.
Cam is 215.5 at .050
.303 lobe lift.

Went to emails from wayyyy back with previous owner. Summit 454 lift cam.

Its the summit 1789.

So its a 272 cam…if i grind it to a 280 ultradyne lobe.
Seat duration is about the same but duration at .050 is 230 instead of 215.

Get roughly the same operating range?
