I have been running a stock short block with Trick flow twisted wedge heads, street upper and lower TF intake, goldcrane roller rockers, trick flow push rods, and an F cam. I would like to stick with that, but I was wondering if any one recommends a well made short block that would work with the TF heads. Trying to avoid having to fly cut the pistons. I was looking at maybe the Ford Racing 347 short block? Like to know what you think or have used with the TF heads.
