Just yesterday I managed to pick up a swell deal... A cylinder head for 30 bucks!!! ported and polished, 3 angle valve job, and no damage to the rocker arm assembly. but here`s the bad... (not really bad at all XD) the lefthand side valve cover screw hole is a disaster. its been previously compounded, and redrilled and tapped. looks like an amateur job at best, so i`ll hafta have a machine shop look at it. either way, it can still be salvaged, and i got a HUGE deal. my plans for a build of it are: Blox dual valve springs/retainers, ferrea flatfaced valves, and unsure what company to go to for a cam. any suggestions, and what hp gains, and max powerbuilding RPM am I looking at? thanks!
