I saw a video on youtube and the guy had 13.5:1 compression, does it really need to be that high! i would appreciate any info that yall can thorw my way. thanks
Yes it does need to be that high maybe even higher like 15:1 and it has to be able to rev to at least 9500 rpms

Agreed

Lock the rockers all together.
On a street car you don't need them.
Get some Skunk2 Stage 2s or Pro1s and 12:1 pistons.
Even with 12:1 compression on some skunk2 stage 2's your peak power wont be until above 6000 rpms. I had these in my stock bore GSR and with those cams/headwork/ 12:1 compression and a lightweight flywheel I was able to make 200 whp and that was when it was tuned with hondata by Jeff from Import Builders.
If you don't fully understand how vtec killer cams work then why would you consider buying them? Do you have endless amounts of money falling out of your ass? What do you have right now as far as mods go? What are your power goals?
