1G Need help with cams but stock head

[757mike]

I need help. I'm building my 1g 92 gsx.
I have everything built but the head. Long story short. I'll be pushing around 500-550 horsepower. Head has hks 272 cams but the rest of head has stock components in it besides it being milled that's about it.
Block has been done with carellio and eagle stuff.

So anyways question is can I run this setup with the head having hks 272 cams and rest of head stock? I need to know before I put engine back in car thanks

Id pick up a cheap set of manley singles or bc1100 and run with stock retainers.
