some questions on building

Okay so as im redoing my head for my b18 eg (still has its cute 1.5)
Im wonderings a few things, Okay so i know you can buy valve springs seats seals valves etc.

but what about rocker arms? (lifters, whatever the name)
i could not for the life of me find b18 lifters. is it to be said that big builds use stock rockers? im guessing if so honda eaither made these super strong or its just not really a weak point?

another thing, what is my encouragement to get new valves (non oem type)
techincally wouldnt titanium retainers, and good springs do the job? or is it about seat to valve contact?

and the keepers... am i to reuse these for reassembly? or is it safter to purchase new (cause theyre probably cheap?)
it would seem to me that you went to the trouble to get the heavy duty retainers and youre using the steel keepers still?

Re: some questions on building

Endyn I believe have developed improved (lighter with a harder seat) rocker arms for B and H series engines. Was an issue with the production units (quality wasn't on par withthe samples) though and they are being redone. B series rocker arms I think are ok, just the H that have had some ware issues. Big builds may replace them, but usually to run VTEC removing rollers.

Aftermarket valves can be stronger (not always a good thing, since instead of bent valves, you get holes punched in the piston heads) and lighter. Can also get flat faced valves for a small increase in compression.

Re: some questions on building

I'm not expert on rebuilding engines but I have been working on building up a D16z6 I bought to about 400 hp. I've found through my research that the lifters aren't really a weak point in the head.

The aftermarket valves are lighter and that helps to spin the motor faster, you know reducing weight helps speed things up. Besides, if you're going through the trouble to buy stronger springs and retainers then why not buy stronger, lighter valves with them to make the head bulletproof. And I'm pretty sure you should use new keepers with new retainers, but I could be wrong, so let someone else figure that out for you.

Re: some questions on building

dk,
I have the d15D in my civc hatch quite quite slow for my tastes, im b16 5speed swapping with a built b18! no vtec, for price options and the mass amount of b18b's noone really wants.

Then the project becomes NITROUS HATCH!
