273 advise needed

I don't see a cam and lifter kit with the E-4 isky cam. Can you verify what lifters you used? Also if the original was solid lifter, how come when you search by year and make all 11 of the cam and lifter kits have hydraulic cams? I found that strange with the isky website.
The Isky site is strange. I will find the cam number and post it here in a bit. I used the Isky lifters they sell.
