What so you think about the Z heads? I can get then with the Ford roller rockers for like $1100. I can get X heads for $900,
Decisions decisions???
I need to run an inline head. Or how much can you get away with on the TW Fast As Cast heads? I think I have read .550 is max.
Ford says that due to the revized water passages I need the new X or Z heads, or modify aftermarkets to have a extra steam hole. Some say it'll work either way.

I have been tempted to have Harold port the GT40P's I have and just run the current set up in the new block. Hell, with a tune and MSD, it should be in the 550 rwhp range. It hit 486 with no tune or MSD already and with the 22 yr old stock shortblock. I cant use the power I have now.
It looks like the bug truck is coming everytime I nail it is 1st or 2nd.
Time for DR's too.
