My friend and I are building a B20/Vtec motor and I had a few questions. I'm going to be using all Skunk2 valve train components, but I need help deciding.

For the Valves... Do I use the standard size, Over sized, standard or High Compression valves?

For the Retainers....I've read about people saying the titanium retainers can mushroom so would you recommend using the steel retainers?

For the Cams....I've used the CTR cams in the past but would like more power. Should I stick with the tuner series or couold I use the Pro 1's?


Here is a little info on the block:
B20 block
Eagle Rods
Arias 11.5:1 CR Pistons
ACL bearings
ARP Head Bolts

The Head is a B16 head and obviously what will go in it will depend on the replies.

Any help is appreciated. Thanks in advance

I am not going to touch the cam question, as it has been covered literally hundreds of times here. There are plenty of dynos posted with a variety of cams - sort through them and see for yourself what makes sense for you.

As to the valves - what compression do you want on your finished motor? If you use the dome volume of your pistons and your chamber volume to calculate your true static compression and you are a bit lower than you would like, go with flat faced valves. Not sure I can give you more direction than that at this point.

Best of luck with your project.
