are they necessary if im only going to run 8lbs on my F20b, i know on d-series they are but not sure about the f20b any help.

 

Well i dont know if this is any help to you, but I own 3 F20B motors (one All Motor built, one stock SIR-T, and another thats just sitting there) and on the built one when i pulled the head off the head bolts had 12 point heads (by comparison, a JDM h22 head i pulled years back for bent valves had 6 point heads) Well an H23 VTEC i built for a customer i ended up buying the head bolts for a 95 Prelude VTEC and when i got the bolts (original bolts were 6 point heads) it had PCB in the part number (PCB is the F20B) and the bolts had 12 point heads. I compared them to the F20b bolts i had and they were the same length, pitch and so forth so i used them (same length as the JDM H22 as well with 94 on the head). That motor is still going.

 

I have a f20b I'm boosting do you know if the h22a head studs from arp would fit my f20b

 

6 year old thread

 

Yes they do fit the h22 an f20b have the same deck height even. lol an who cares if 6 ur old thread . Hey share the knowledge good luck on the build Pedro. I like to see

 

LOL....NAR is the thread police and he has honed his skill very well I would say.

 

Hey so I have my f20b apart and I'm putting the arp head studs from am h22a in and when I screw them all down one in the middle of the block goes about 1/4 to 1/2 inch farther down. I'm wondering if I should screw it all the way down or back it off and level it out to the others. Opinions?

 

I would make sure all the holes are cleaned and tapped.
