Oversized valves

Hey guys,
Have now got myself a spare 15m head and a jap spec manifold, am planning on doing some work to it, valves, springs, camshaft etc. Am I able to get oversized valves for it?? And also is there anywhere that does lifters?? Price not really an issue lol, and if available, what gains would I get??

You can get whatever sized valves you want for it.
You have to talk to an experienced head tuner for info on whether larger valves would be worth the effort and money.
Lifters??? No lifters in these engines.
Price better not be an issue to start with because it WILL be after fitting larger valves AND seats and having the porting dont to justify it all.
Easy to say the head will be worth far in excess of the car!!!!
good luck tho.
