Okay I've had my b18a1 head port and polished, 3 angle valve job, Brian Crower bronze valve guides installed. Already have my BC valves and BC dual springs and titanium retainers. viton valve seals installed. OEM seats. I plan on going with the Brian Crower forced induction cams and plan to make 400hp on this valve train. But is everything going to sit down and fit right? I've seen some threads talking about clearance problems with the BC springs and had to have the seats milled or something.... the rockers arms are going to be adjusted properly. So that will not be of worry. Is there anything I should know before I start assembling the head? And I don't HAVE to go with the BC cams I'm open to others opinions and their suggestions. And what valve locks should I get? I understand ferrea is pretty good. And they make a radial groove and hylokeeper. Anyone know the difference? They are the same price. I've also see some builds where they micro polished the camshafts? What are yalls opinions on that?

 

Cmonnn somebody has to know something...

 

Be prepared to degree the **** out of those BC cams... I have the exact same ones and had a good little time doing so. They are by no means a drop-in cam. If I had it all to do again, I would go with Crower's cams, not BC.

Not sure about the springs/retainers, but usually milling the seat is for when you start running HUGE lift cams and should niot apply to your situation. I have Crower springs/retainers in my head.

 

Gunmetal_B20_Hatch what valve locks are you using in your set up?

 

I honestly do not know... Its a P8R non-VTEC head that I bought already assembled only missing camshafts.

 

stock keepers are fine.
I would still inspect them for any unsusal wear. I've seen some H & Bvtec ones develop a flat spot.

Worse case just get OEM ones which are $2 a pair x 16 pairs.
Ferrea are nice but spendy & overkill for most setups.


as for milling the seats, i've never heard of that
I run Rocket Motorsports snap fit springs in my brothers B20 & rocket provided us thicker seats to increase spring pressure.
