Well... i have AFR 210s.. and my corner screws are giving me a hard time.. the cup will simply not fit...

Someone said the 234-4301, sadly i want to get this done today to have that engine in tommorrow morning, these are the 12point head nut.

I was thinking on:

1) at a last resort, go back to arp bolts
2) buy a set of 12point nuts if available...
3) use studs and bolts??????????

that is my questions.. what would be the couse of action you would choose.

Keep in mind that i have an event the 11th of december...

Do i grind down the afr 210 on the corner to make the 6point cup fit? or do i simply wait till tuesday to bolt in the heads and drop in the engine?

Can i use only bolts on those 2 corner bolts... or use bolts all around...

any ideas? suggestions??

the springs are thin enough, so only the spring locators are getting a BIT on the way and that can be ground a bit also.

I have air tools, air grinder and a big air compressor...

WHat do you guys suggest?

 

get the 12pt nuts

 

I had the same proplem. Cant exactally say how I fixed it, since the motor is out of the car and torn apart now.
