this friday i start my vacation again and i've been looking at those l35 heads sitting on my the engine in my parts truck. i put the heads on my parts truck when it was running and that took some effort to put the exhaust manifolds on and involved me buying a new tool even. are the manifolds on our truck as hard to change? i thinking about doing a basic rebuild on my l35s before i put them on with new springs and valve seals. anyone got any input on doing this stuffs?
 
Re: head swap

Some have had problems with the holes lining up when they put them back on. You may need to put them in the oven before reinstalling them.

Re: head swap

The Turbo bolts can be tricky if on a rusty truck. The driver side power steering bracket is a PIA to remove and further PIA to put back all the bolts (I ommitted one).

IMO I wouldn't put your effort into swapping L35's when your truck is only running 90mph trap speeds. Stock is 96mph or so. With a propshaft and an ulitmate chip it should right around 100mph.

Re: head swap

i swapped heads in 2 days during the week (without removing fenders). if you are on vacation you should be able to do it in 1. the oven trick is a good idea, i milled my holes longer. if your truck/cam is stock i wouldn't bother with a rebuild (i didn't) but others may disagree. this being my second build i just put some big ass valves and springs in my vortecs... wanna talk about buying tools???????

in my case when i did the first swap i created and found some other problems...

Re: head swap

well mainly i was wanting to put new valve seals in these heads and while i had them apart do a little flow work. i've located a driveshaft for my truck in the salvage yard and i believe it's actually a gilbert shaft. the pictures they sent me look identical to the pictures of the gilbert shaft i've seen. and i'm waiting on more of the ulitmate chips to be burnt. i'd like to be able to do all three at around the same time. ditto on my intercooler pump. our local truck performance shop is working on getting me one.
