I am in the process of buying parts but need to make sure I get the right stuff so as not to waste money... So here is the deal.... I plan on making no less than 350hp to the wheels and it IS going to be a drift/ weekend toy. I was thinking for a rebuild o the head of going for a port-n-polish, BC springs retainers, valves and ARP Studs. I also am having cam issues. Also what is the best company to get these parts from??? I heard that BC cams aren't as good as some others and I don't really want to be buying a name. I heard 272 cams for exh. and int. are really good but need to doulbe check with anyone that has used this or a moderator. on the valves and what not...what sizes should I be looking for and I also have seen that BC has a Dual Spring kit out(anyone ever used these?).

for the block I was going to go with forged internals and thinking of going BC again. Forged crank, rods, and low comp pistons. Need help on picking these out. what would be a good compression ratio for a kat on stock bore or maybe .20 over, with aabout 350-400 whp and trying to run 7psi low and 20 on high. Keep in mind I'm shooting for bullet proof here. I saw some pistons that were 9.0-1 compression. But the crank and ****, I should be ok to go ahead and buy the standard crak size in a forged setup also standard sized forged rods? Also is BC really as good as they say or should Eagle and Comp be better? alot more Q's to come thanks guys...

Well, whatcha got for fuel/ignition mgmt? What turbo? BTW, people have made 350whp+ on a stock motor. I know you said you want bulletproof. But your plan seems like overkill for 350-400whp.

Most pistons Ive seen for the KA are btw 8.5 and 9 CR...
