Short story to long questions. Bought the car had it for a few years went turbo two years ago popped a head gasket lost my garage and it sat in a barn for two years. Before I stored it i took the heads off it and that was a bad choice because it left me with alot of missing parts and such.
Fast forward to today.
I found a 306 locally with,
89 HO engine
these heads ---> Ford
Speed Pro forged pistons -2.5 dish
Rods were R&R'd with ARP bolts
1.7 Crane Rockers
I checked a couple mains and rods for clearance and they looked good. Checked PTV clearance and that was good also. I was told that the heads were decked to 63cc and all the machine work looks recent. I know the setup ran in a carbed car before because I had to change out the front cover.
I got it all together with that ford racing gasket kit and it ran like a champ even with my tune being a little off because its for my stock engine setup.
I got into boost one time , kept my eye on the wideband and it stayed ~11.0 to 1, and I popped a head gasket. I used ARP bolts, torqued them down correctly and everything. Only made it up to 10 psi. Wastegate has a 13 lb spring in it.
SO, with all that in mind I ask all of you. What would you do?
My head options are as follows
1995 Cobra GT40's, untouched, un-inspected, stock everything
The power head D80E's un-inspected
I have searched and read just about everything on head gaskets. and come the conclusion that its between the Fel-Pro MLS 1011 or Fel-Pro 9333pt2.
I am at my wits end this time. I got 10 miles out of the engine this time. hoping that I can get the rest of the summer next time.
