I forgot to ad that magnums are better than a 302 head unless you need a smaller port volume, for whatever reason that my be.
Facts , they are both are crackin sob's , most 302's ive seen crack all the way to the closed deck from the exhaust seat. Ive found 3 sets out of 8 that werent cracked.
In a way its sad people cant grasp that a magnum is like a 302 is in ported form.
But it cost more to use the magnum head.
Btw, im gonna call you, cause im pretty certain we are mostly on the same page and I bet there wouldnt be taking opinions sideways like on here.
