Flipping it over was a no go. So I went ahead and order a 64mm rocker assembly from Scrappys. Hopefully it will be here Friday or Saturday

Got the 64mm rockers today and looks like that fixes my problem! Waiting to mount it up till I call scrappys tomorrow and find out the status of the customs seized orders. Don't wanna put the engine back in then get the a9 the next day.

i cant even make out what you are saying....!!!! i know for a fact that the big valve head is better than any competitor out there...so is the head what you are complaining about? or is it the fact maybe you need somebody to show you how to properly build a engine? and scrappy's stuff is deffenitly not crappy...........................

Ok so out testing it today seems it's not right yet. Thinking I might need a bigger jet. Just seems sluggish and not as fast as before bbk and big head. Also seems to be running extremely hot, I'll post pics of the plug tonight. Thanks for any help.

All my parts seem to be excellent quality from them. Any ideas on if I need a bigger jet or can I fix this by adjusting the a/f mixture screw

make sure your not a tooth off, what jet are you running with it, scrappys big valve heads move alot of air require a larger jet to perform properly

I believe the cam is in the right tooth. I am running a #  jet. Will adding the a9 cam require a bigger jet then what I would need now? Cause I'm still waiting for the a9 from scrappys, just don't wanna get it right for this then put the cam in and need to re jet again |

 - 92 jet with the big valve head stock exhaust, the big valve head works best with open air filter and hi pro exhaust |

Ok, no harm in running a slightly bigger jet then needed right? Just burns more gas right? Just my local shop charged me $17 bucks for the # so don't wanna have to buy a bunch |
