Just be aware, the 120amp is thicker than the 70/90amp.

I actually still have a 120amp sitting on the shelf because the backing was just a little too thick to clear my edelbrock heads with MT valvecovers. The 70amp fits no issues

I think I read that with Edelbrock heads. I have iron heads. I'll try and see if it works. Wonder if the 90 is smaller than the 120
