i have a 30% bigger radiator (aluminum-new) and i still get fluid on top of my pipes wen hot,as did the stock one. im more worried about stayin cool then compression,would it be a good investment 4 me. i have the 30% radiator-(2)in line coolers,one on in and out lines,and i run engine ice coolant,thinkin it would help. nothin. i hear all good about the 21c.c domes,but since ur the only 1 i have heard on the oposing side,wat would u think? thanx
