    Question

    If you don`t mind me asking, why? Was someone doing a seven angle cut and messed up? Or did you drop a valve.

    What else are you running besides gasoline? If you don`t mind me asking. Hardenned seats don`t pit very easily without some form of "other" injection. Even high rpm doesn`t cause pitting more likely recessed valves.

    When I first had my head off at 10 I noticed it around the seat. then now agiain but now into the seat. almost to the valve lap. mods rr level 1 plus 42's New sc fan, thru hull. i think its from heat. to lean. gets hot after 15min into race and i think oil in boiling.

    Damn, hardenned seats pitting from heat? Gotta be really hott! I run no thermostat. Its hard to get the air out. Are you sure your purging the cooling system good enough? I thought I was but found out different yesterday. It took about 15 mins to overheat. Popped the puke tank (not fully cracked but partial) and steam like a muther came out for a solid minute. Took another gallon of seawater to fill it. Then it was fine. Filling with orange anti freeze now and bringing 2 gals of distilled next time out to purge system. That`ll do it for me.

    You can get them cut at local machine shop just need a 3 angle valve job and ADD .030 shim to the springs. You might have some weak springs also. Add a little race gas when running bouys!!!!!!!
