Two 360 builds idea for heads

Yeah, that LA definitely looks like a lot of fun! On a side note, my very old school machinist tells me to hold about 6500 rpm limit on the cast crank bottom end. I’m sure there exceptions to the rule, but that’s what he suggests with the stock crank.
I guess I was asking about the heads. If I should go aluminum or cast. Only cause I can get my hands on a new set of cast 2.02’s MP5249574 or I can wait till the sale for speedmaster and go aluminum. Or say the hell with it save my money and redo what I already have 308’s or 915’s. I’m conflicted. I have parts everywhere in the garage.View attachment 1715711485 View attachment 1715711486
For the LA I have two hydraulic cams that may not be ideal but I have em. A performer RPM 7177 308* dur. 112*CL 488”lift and a MP4286630 280* dur. 110*CL .474” lift. The MP is new but has rust on it that needs a lot of cleaning maybe a vinegar bath and see how it turns out. Wish it was stored better. 6CCAF74B-C750-4C1B-B25C-2B0AE5E3955B.jpeg
