supertech makes skunk2 parts but are the retainers the same?
i am going with skunk2 pro2's and i know there is going to be some clearance issues with the valve guide/seal to retainer clearance which crower makes a retainer that is +.060" higher so theres more clearance there and you need to machine the rockers. Now skunk2 makes the retainers with more clearance from retainer to valve guide/seal but the retainer still sits at stock height. I was jus wondering if the supertech retainers were the same.

 

go with RM GEN1 valvetrain and dont worry about modifying the rockers

 

you dont need to machine rockers with the skunk2 pro series too.

 

I heard the skunk2 team doesn't even use their own stuff?

 

you should read my post

If you are using the Supertech dual valve springs, then you will need to order different valve guides/stem seals from Supertech that work with their dual spring setup. But if you are using the standard single valve spring set, then you can just re-use stock.

 

Also, I emailed skunk2 reference their (or whoever makes theirs) titanium retainers, and the Rep told me to expect to change them out at 20K. Just for your info bro. Good luck.

 

yeah i know you have to change them...most people say about 30k but whatever.
ill be using the ST dual valve springs as well with their retainers.

 

Would clearance also be a problem with skunk2 stage 1 cams and supertech valve springs/retainers. Or only with the higher lift pro2's

I run the Stage 1's with a pure OEM valvetrain.....~20k miles and still perfect.
Im a fan of anything SuperTech, but when I do my head again it'll be RM VT for sure.

Why is this ?

 

I think the skunk2 retainer is also offset like the offset crower. It shows on their site that its supposed to be shorter than a stock retainer on the underside, but when I set it next to the stock one it looked like it was the same height. What I THINK they do is make the tapered part where the valve lock goes a little wider, causing the retainer to sit a little higher on the valve stem which is what crowers offset retainer is doing. Skunk just doesn't advertise it that way.

Thats just my opinion though, I didn't get the chance to measure anything before I sent my head out to get ported but I'll have it back this week hopefully. I can take a valve out then and compare all three.

 

With Pro 2's, Skunk2 valves, ti retainers, valvesprings, you have to have the rockers machined

??

 

Any definite answers?

 

bump...for this being the first time ive heard this.

can anyone clarify?
