Thanks Neotech, I appreciate any information I can get. Do you happen to know of any of those old threads that have head prep info? I'm having some trouble finding them.

As long as the SCR numbers I'm getting for this head/piston combination are correct (~8.5:1), then I'm not worried about that part. So the liners tend to jump out under pressure? Thats a good thing to know.

Hey guys. I just got my first S30. I've been wanting one for a long time now, and one came up local cheap enough that I just couldn't pass it up. Its a 77' 280. The usual heap of rust, but its MY heap of rust. While I'm mitigating rust damage and replacing 30 year old suspension parts, I thought I'd make some decisions about the engine so I can start amassing all the necessary parts. I have been searching and absorbing as much info about the L series as I can, and a couple questions have arisen. I'm sure they have been asked before, but I certainly haven't found clear answers. I'm working with the current parts. L28E F54 block with P79 head. Flattop pistons. Haven't identified the intake manifold yet. R200 with CLSD. 5-speed trans....which I haven't pulled numbers off of yet. Planning on running a MS3 and relativly large turbo (something like .70ar cold and .86ar hot). 1. Ideally, what prep work would you do on a P79 head prior to application on a moderate turbo setup? 2. How does the stock cooling system hold up? 3. What fitment restrictions can I expect to deal with regarding the l28et exhaust manifold and aftermarket turbos? Any tips or suggestions?
