ARP Head Bolt Kits
Hello,
Does anyone which ARP bolts (part # or kit #) to get for a stock 99' Mercruiser 7.4L MPI? It's a Gen VI with the oval port heads.
I overheated badly this summer and for good measures I am going to replace the head gaskets and figured why not replace the head bolts. I doubt they are much more expensive than OEM Merc bolts.
Also everyone recommends ARP thread sealer?

Re: ARP Head Bolt Kits
ARP Part numbers:
Cast Iron OEM Standard 6 point #135-3601
12 point #135-3701
Pro Series #235-3701
Stainless 6 point #435-3601
Stainless 12 point #435-3701
I'd go with the standard 135-3601 (about $50 mail order), unless you have made any modifications to this motor.
