Well my car will be lsvtec sometime next week an i ran into a problem with choosing a cam for my set, if im even able to run aftermarket cams. Well its a stock block b18b with a b16 head thats been milled a pretty decent amount. Like there is a spot on the back of b16 head that i was told that once you milled up to this line on the head that the head is no longer good or atleast honda says so. But basically from my head being milled that its damn near reached this line on the back of the head. An from what i was told a few people told me that i cant run any kind of cam besides my gsr because anything more aggresive like itr cams or blox type a,s2s1 would be dangerous because the ls pistons dont have good valve relief clearance. So i was wondering if there is anyway for me to measure or check to see if i can run a different set of cams because i have gsr cams in my b16 head right now. Oh yeah id like to get a opinion on the setup if possible too, id like to make 180-190whp with blox type a cams.

I would look into doing somthing with those stocker LS rods first and foremost.

Not too many cams will be happy with low compression, LS pistons try some p30s imo.

No offence but make your motor right before you try to make it fast.

 

You're not going to make any power with LS pistons and a DC header, especially not their 4-2-1.

 

based on what this guy has, what kind of power do u think he'll be making?

 

Yeah i was told that since my head has been milled twice now, on the stock ls pistons my compression would be 10.5 compression. Atleast thats what inline pro told me out in maryland. Oh yeah an i dont remember how much the head was milled the first tiem but the machine shop who is milling it not is taking another 0.010-1.015 off it. My guess is the head is prolly around 0.040 once its all said an done. An i will be using a stock honda b16 head gasket.

 

i though all b series use the same head gasket, same part # and everything

No.

Also, to go from 9.2:1 to 10.5:1 in compression from milling, that's something insane. If that were indeed true, you are definitely going to need some adjustable cam gears to compensate.
