It seems as ive lifted one or both of the heads while it was on the dyno (i forgot to zip tie all the vacuum lines especially the one going to the FPR, popped off and ran lean/detonated). Now the car pushes coolant out the coolant overflow resivior. Atleast the spark plugs aren't wet.

I was wondering what parts would i need to buy other than a head changing kit, i was told to stick with stock 4.6 2v head gaskets but to get 03 cobra block ford tty bolts. Any other parts i need? Ill try and get the heads to a machine shop to make sure nothings cracked and that they are still reusable/not warped.

The motor is a Built 03 cobra motor (w/ DSS extreme pistons) with about 2k miles on it, stock 2v heads, new timing components (2k miles) in case it matters.

I strongly suggest using ARP head studs as apposed to TTY bolts

i heard those need to be retorqued after a few heat cycles??

lizzyfan

Who told you that?

avexhype

an engine builder... also made a double post over on modularfords and some guy said so also...

Ive never heard of that. I know a few people who have arp stuff, and they've never retorqued the heads.

If it was a brand new short block it's not a bad idea but in your situation, no.

I run ARP and don't worry about a re-torq.
