Using Guides with Self Aligning Rockers?
Using Guides with Self Aligning Rockers? Whatsup everybody. My engine is apart and we noticed that my rocker arms are only screwing in 4 threads deep. My mechanic says using guides would help move things up so that the rocker would have more to grab on to. I believe my rockers are self aligning so if I add guides will that cause a problem? Also, is there a way I can tell for sure that the rockers are self aligning?

You don't use guideplates with SA rockers. They could end up fighting each other for alignment control. What rockers do you have? SA rockers will have little tabs on the sides of the end that meets the valve tip.
Hopefully you heard him wrong, because if you put anything between a bolt face (washer, guideplate, whatever), you REDUCE the number of threads into the material. Common sense.
The OP is talking about putting guideplates on to increase the amount of threads that his rocker arm nut/poly lock will engage, which in this scenario is correct. Adding washers (not guideplates) to the bottom of the rocker stud wll raise the height of the stud in relation to the pushrod/valve spring increasing the number of threads available to engage in the polylock while reducing the number of threads engages into the head. Most rocker arm studs include washers to use in lieu of guideplates for self aligning applications.

i guess both ways work. washers are just less expensive and will not really have a negative effect so i don't see why i wouldn't use them. the studs will still be deep enough into the head with the washers.

stock heads ported and polished a while ago. i believe the pushrods are stock length and the valve diameters are 2.02/1.60 but as far as lengths go i don't know. probably not much help lol. its ok my mechanic will measure everything. i was just looking to see if i could get an answer before i pass by later in the week.
