re-installing cylinder heads

Elmo370z · 02-10-2016, 08:52 PM

When the new jwt cam comes out, I'll be order them with ipp heads. They will install the cam and upgraded valve springs. Can anyone inform on the procedure of removing the cylinder heads and re-installing them. Vvel reset etc... just a quick synopsis?

Elmo, out of curiosity, are you planning to pull the engine to do the work?

You're asking for disaster bud. You'll never be able to evacuate all of the fluids from the engine sitting in the bay. You're going to have coolant in the masses everywhere in your bay the minute you separate those heads from the block. Also, you risk getting it into the cylinders; which isn't an issue as long as you can guarantee you have good piston rings to prevent it from making its way to any sort of oil or bearings. Even the slightest bit of coolant inside oil will break down the lubricating properties dramatically. Most importantly I think you're under the impression that the cylinder heads can be assembled intake+exhaust cams, ladder, and bolted together as one unit then torqued down to the block(just an assumption from the wording of your OP) which is not the case. The head must be installed and torqued then in the following order you can place: exhaust cams, ladder assembly then the rear timing cover can be placed back on to begin with reassembling the I-E cam timing and cam-crank timing.
