I have a 95 (Honda Civc 95 Special edition version) 16 valves. None-v-tech.

I am changing my o ring does anybody know which is a good one
for the head transfer but also restore my horse power because in the
dyno the car show 123HP it sopose to be 125 but, I want better cylinder
heads and better o-rings for my cars. Does anyone know for a good
quality Aluminum cylinder head which are light but also give a little
power and very long lasting for under $700CAN

 

Whoa, whoa, whoa. Slow down. Which o-rings are you changing? A loss of 2 horse is nothing to get freaked out about. Regular maintenance should recover your lost 2 HP. Good thing you've strapped that to a dyno, or you'd never know! There's nothing wrong with the stock cylinder head. In reality, to purchase a fully custom head to work on your motor would cost way more than you'll ever be willing to pay for one. Just take the head and build the top end. You should be able to do a fairly decent upgrade for the budget you've got. I might suggest a mild port and polish and maybe some valve work. Good luck.
