How much did everyone pay? Was it worth the money? I want to have this done while my engine is apart.

Main thing with heads, make sure to get the valvetrain to support your rpm's and heat

ie. inconel valves, bronze guides, etc.. seats and retainers...

they will, need guides... and the heat associated w/ FI, especially the area you are heading, those valves will be your weakest link.

inconel valves, all of them, would suffice.

your springs and retainers are good to go ;)

link to those valves and guides?

I am going to do everything right the first time so I spend the least money possible down the road.

port work wise, I would recomend richard at West Coast Cylinder Head... he has about the most state of the art cnc porting and flow anaylsis programs you can find.

expect to pay for good work.

****-- Richard will charge around $650-1000

but he will flow bench them first to see what he's got.. he then molds the port/chamber/port in a cnc program and blends the runner the the valve seat.. I can tell you he focuses on guided bosses alot..

worth the money..

Juco-- I understand your reasoning, BUT.. I picked up 27 peak and 12 average horsepower as well as 20+ftlbs ALL the way from 1500-7000 from JUST a 5 angle, a SLIGHT bowl blend, and polished (NO shaping at all..) intake runners.

in all, about 4 hours of work in both heads... paid $40 for the work from Smiths Machine in VA.

case in point, head work is VERY productive in F/I apps... granted I know guys who have made over 1000 rwhp with STOCK heads.

the most important thing about porting heads on F/I vehicles, more average power OUT of boost.

The porting will also lower boost! :)

this is making me shy away from heads
Like Chad said, valvetrain is more important than the porting. I still think you'll be okay unless you want to rev it more than 6,500 RPMs. I mean sure something could break without going higher than that but it's not the rule.
