as far as i know 5k's have hydraulic lifters but solid lifters would better suit the application?
5k's have dished pistons? if flat top pistons were obtained could a worked 4k head be used?
just how much compression is too much compression?

that depends on rpm. some ppl use hydraulics but up high they may pump up... if you go solid you need a lightweiht option, not just lockign the original lifters
yes. yes. no real difference in ports, but free higher compression (after pistons).. a 3k head could also be used if hogged out a bit. 3K CCV=33mls, 4K CCV=36mls
that depends on your cam. it's dynamic compression that is important..
with the combustion chamber mods on my head (see my page), and camtech 609 cam (435 lift, 231/235@50thou) i had 10.2CR, but i think i could get away wth 11 befor epinging.. less duration = less compression (required)
