1G GETING MY CC'S (Combustion Chambers) O' Ringed

[SleepOnThisGs]

so I just left the Machine shop here in Oklahoma (marks machine) they have a couple 4g63 engines running in the low 10's. I need to know wich Fel Pro Head gasket PN# preferred I need, or should I stick with the cometic HG. also bolts or studs. its a 6 bolt, and im finding a lot of confusing info on weather or not to buy new bolts or just get the l19s. im only looking for about 400 hp a evo316g probably around 25 to 30 lbs max boost. 272s maft and ecm link probably some fic 1000s. evo 9 fmic. blah blah blah. please educate don't adjucate thanks....

Why are you getting o'rings?
Oem composite and arp's will do the job just fine. You can go with l19's for alittle extra insurance. You definitely need ecmlink or a good way to tune. And a fuel system to keep up with the boost. What's with the evo9 fmic? Lots of better options that will bolt in than that. Check out the 16g thread.

the evo 9 fmic was free, don't intend on having it long, im eventually going to put more than 30 lbs of boost on this engine when I swap it into something rwd, Mark at marks machine shop has a couple 4g63s in the 80lb of boost range and has a couple engines he built pushing over 1200 hp. I don't need all of that, but he told me he would deck the block and mill my head so I might as well o ring it for the future upgrades I want. ive been reading that the arps not the (l19s) are weaker than the stock 6 bolt head bolts, well not weaker they stretch easier than the oem's. and I just need to know which gasket I need for o ringed block since he's going to do it free.

Gotcha! I'll ask my buddy Dante what he's using on his oringed block . I believe it's a oem or felpro. He had a hard time getting it to seal and pretty much tried every gasket . The thing about arp's is that there studs. So it changes the way the head is held down. I haven't heard about them stretching easier. I have them in all my cars and no issues. Even reused with no issues. I did go with l19's for my hx35 setup just for that added insurance. There's also h11's now.
