I have a guy selling me a set of ported 799 heads that he said he will install some OEM LS7 springs he has. I am trying to put these heads on a LQ4 shortblock to get around 500 hp with proper cam. I read that these springs in this head will not work due to height of spring at rest compared to stock 799 springs. Any info is appreciated.
