Iv tried asking this in the exhaust forum many times before with NO luck, so thats why i am posting this here...

im am installing SLP headers. how many of what sized bolts do I need?????? just for the headers going into the heads...... PLEASE HELP ME

 

generally its 6 on each side, that makes 12 total

 

thats the only thing i DO know............

What grade should i get?

 

Order an arp grade 8 bolt kit from summit or jegs. That's what I'm using and they work great, good quality and easy to put together.

 

Get the Stage 8 locking header bolts....you'll thank me for it later.

 

Do your self a favor and spend the extra money on some stage 8 locking bolts. I can't get the locks on mine, but the hex head in the middle of the bolt helps in tight spaces.

Most bolts that go into the head will be generally a 3/8- 16 coarse thread. Don't quote me though.

Some of the bolts will have to be longer, get them from home depot or somewhere close and get grade 8 bolts.

 

can i just use regular bolts with lock washers? thats what the guys at speedtek told me to do since he said locking bolts were a pain to install. or maybe use some thread lock?

 

I had the Stage 8s on my 1 5/8 SLP's. They SUCKED. No way I could get them tight enough with a crappy allen head wrench. Forget about getting a wrench (7/16 I think) around them to tighten with the way the SLP headers are made. I eventually bought the SLP bolts and pulled the headers, got the grinder out and "clearanced" the header flange to allow a 3/8" wrench on the SLP bolts. Now I can get them nice and tight. Don't waste the money on the Stage 8's You can't lock em down with the SLPs.
