is there a kit I can buy for the Vortec heads so I can use the LT4 hot cam or do I have to buy the comp cams part# 26918-16,648-16,787-16 separate

There will be no Comp "kit" ; you just buy the parts you require

I knew I couldn't find one anywhere with the parts I thought were the ones needed but I had read on here somewhere where someone was talking about a kit they used and thought I would at least ask

I done this swap awhile back.

There is no kit, but I have a thread that shows everything you will need and where I found the best prices for it.
