I am planning to purchase BC 280 cams with the springs and retainers. I was wondering if I should pull the head off and work from there or should I leave the head on. I have read the install, but I am worried about dropping those small parts in the engine. Or should I forget the whole spring/retainer thing and get the 272?

 

Its all personal preference.

There are several more things to take off to pull the head then of course you need a new gasket. If your doing studs at the same time then by all means do it that way. If your just doing the cams and springs then all you need to do is hook up your air compressor to the cylendar your working on via the spark plug hole and pressurize it so that the valves are forces up. Its that easy.

 

I had done some research on this, and found people had alot harder time doing dual springs with the head still on than single, I think the BC's are single springs...

 

Yes, the springs are single. What tool would be the best to use?
This one. Schley Products Universal Valve Sping Compressor (P/N SP 91400)

or this one. It's snap on.

Your links don't work.

 

Links fixed!

 

i thought BC's were duel spring. can you get them duel if you wanted to? when i got my ARP head studs put in they didn't take the head off they just did one at a time. it saved me from having to buy a new head gasket. GL to ya bro. let us know how it turns out for yea

 

I am most likely not going to take off the head. I'm pretty sure the stock head gasket and bolts can handle 28 psi on stock turbo. I will probably follow the air tank thing.

 

i ran 28psi on stock head bolts before no problems i havent heard of much with head lifting on evos but i did upgrade when i put on the race head just for insurance

 

That first tool is the way to go. I have a cheap crappy autozone one that you have to turn a knob on to compress the spring. I've done several heads with it and it works, but the lever type ones work sooooooo much easier and faster.

 

I have one I made, I can either make one for you if you want to pay me to make it andship it to you (its works great and is alot cheaper than the snap-on), or if you want to wait till my friends done with it, I would be willing to sell it to you. PM me for more information! I can also rent it to you if you would like to go that direction.

 

I can vouch for the Snap-On tool. I used that one for my valvetrain install, with the head off of course.

 

I use the Schley tool when the head is on or off. I have a bench that the head gets bolted to that has pads that hold the valves closed. If you are installing studs also, I would pull the head. I'm not a fan of the one at a time method. GL either way.

 

A ittle off topic, sorry. Is it a must to run aftermarket cam gears with those cams?

 

No
