Well my valves got bent and the head is coming off. I don't have enough money for a port/polish, but a multi-angle valve job is do-able. My question is, is it worth it? Are there any real gains?

yeah you should see a gain. Mainly because you'll have new valve seal/seats that will hold compression better thus making more power. what are you compression# like?
BTW if only a few valves are bent that doesn't automaticlly mean that you messed up your head or valve seats.

If you can try to take car of the port & poslish and VALVE job all at once. save time and money

 

Quick dumb newbie question, I am going all motor with my d16y8 (dont flame), and I just picked up a ported and polished head w/a 3-angle valve job. If I wanted to put in new valves, do I have to go get them shaved to fit? Thanks!

 

it is worth it, most of extra air flow is picked up through a good valve job

i have an extra set of standard sized rev valves for 200 shipped if u need them

Yup

 

grrr, how much would that cost? Thanks!

 

Not sure on the cost, check with your machine shop....they probably want to clean/resurface the head, too.

 

225 w/4 angle valve job or 50 w/o. includes back-cut on valves.

 

for power:
intake side: multi-angle
exhaust side: radius
backcut valves
