cylinder heads valve seat cutting, engine work....etc

now im planning on doing some work on my z over the winter,

 

im going to be rebuilding the heads with new seals etc and was wondering on valve seat work?

 

if the valves are all ok can i get the valve seats recut (3 angle jobbie?) and use the original valves? will they lap into the newly cut valve seats ok?

 

 

also while im at it i am ordering some weisco piston rings for my 87.5 mm wisco pistons. what is the easiest DIY way of gapping them so i get the faces really square without spending out on a special grinder which i would only use on one engine build?

 

 

main bearings and rod bearings. would acl race series standard (depending on condition of crank of course) be ok to use or any opinions on other makes of bearing sets?

 

all help greatly appreciated.

Perhaps I should have asked which fluffy dice I should buy . Pink red or blue, at least then I would have multiple replies!

 

 

come on can any body answer any of my original questions?

Just for reference Gaz, Silverline doesn't use the forum anymore.

 

As for the dice blue please, you know it suits red well.

Hahaha. Thinking pink myself. The question was open to all but wanted some professional advice if they are kind enough to help.

Yes you can have the valve seats re cut and the valves lapped back in, while your refreshing the head strip the hydraulic lifters down and clean them out easy job,

 

ACL bearings will be fine if the bottom end hasn't been knocking the crank should be fine just have it polished to give it a perfect surface
