Can any one tell me what these casting numbers are?

This is a 4v head but i want to know what year and the application.
Head- RF-XL1E-CO64-AE<-this one should be right...Now the its either a 6O, CO, or 60, C0
RF-XL1E-6O64-AE





This is a 5.4L but i want to know the year and application as well.
Block- 2L1E-6015

My long term plan would be a 5.4L 4v in a 99 Gt. I have both the block and heads

 

1998 & Later 5.4L Tumble Port DOHC

 

Do you have any more information on them, are they junk or what?


Look at the heads that will be handing you your A$$ paul!!!!!

 

They are not junk, the problem is getting an intake manifold to match them... the ports are huge! I have been considering doing a 5.4L DOHC swap. IDK though, it seems like alot of work and the power gained compared to the weight added just doesnt seem to be a good deal... Still doing research though. Good luck man. I think i might keep the 4.6L. Im thinking of getting cams soon, new stall, and add another 50 shot of nitrous. Keep dreaming

 

MMR makes a intake for the 5.4L DOHC heads that should fit this application. I have thought about this a lot weight, hood, wiring ect... and trying to get all my facts straight before I invest any money into it. The block was given to me and the heads were laying around at the shop. So just time invested right now and ZERO dollars.

I really want to go all out with this with cams, blower/turbo, nitrous.
O and I make my dreams reality.

 

Haha... well then whats to think... you have it all given. www.modmaxracing.com has cheap rotating assembly for the 5.4L. Wiring might give a problem, but nothing your shop cant do. Didnt know MMR made one. Well man, ill let you be the guine pig and ill make up my mind after you.

 

The money i do need does not grow on trees.
