HKS 264 8.35mm lift cam shaft....help needed!

[lolali]

Hi all.....

I'm new to this forum, not entire new though, had been following this forum for quite a long time, but i've just registered as member recently, and this is my first post here.

I'm from Malaysia, I own an AE86 with a small port 16v 4A-GE engine completely stock, except for the exhaust manifold, it's a 4-1 manifold, the engine is running smooth n doesn't got much problem on the engine itself.

here comes my question, I've bought myself 2 HKS 264 8.35mm lift (According to http://www.club4ag.com) cam shaft, n thinking to do a little upgrade to my engine, I wonder if i install the above mentioned camshafts, can the original valve springs endure the now higher lift cam?

It's understood that many would recommend me to replace the original valve spring with the after market one, due to financial constraint, after market valve spring couldn't come together with the camshaft. So, i'm seeking answers/experience from who has done this b4, whether it works or not, if it works, does it last long enough?

Sorry for the english, i hope i've stated my question clear enough for u guys to understand.

Thanks.
