Is my B16 head ready for boost? Help with identification
 

So i picked up what i thought was a stock PR3-1 B16 head for a great price. Opened it up to build it, and found the first thing, 96+ GSR cams. So a plus....

I'm not too familiar with the valvetrain and what it looks like stock so......can anyone tell me if these are stock B16 or GSR valves? They look pretty decent, you think i could just clean these up and reuse these? On a side note, the valve springs had Dual springs intake marked green and single exhaust marked white.

Also, take a look at the ports, is this what a normal B16 head looks like or has this been ported? Also where the valve seals, has this had a valve job or does this look stock?

Trying to figure out if I should order Supertech valves, springs, retainers or if I can reuse what i have. This will eventually be on a built B18b bottom end. Looking for 400whp.

Also, is that a 3 angle valve job or do the stock seats look like that with the color difference? I just dont know.....

your valves look ok to reuse. b16/gsr doesn't matter, they're the same. only ones that are different are type r.

Supertech valves, springs and retainers would be a good idea if you have the money to spare. If you're not revving that high you should be alright with your stock setup as far as I know. The idea of upgrading is to combat valve float which is more likely to happen the higher you rev your engine.

the head looks stock other than the cams.Plenty people put gsr cams in a stock b16 head
