Hey everyone im new to the site and i was looking for some advice on a teksid 4.6 build, i planned on getting trick flow twisted wedge 2v heads but i wasnt quite sure what the difference between the 390/375 top end kits and the 380/375 top end kit with 44cc heads and the 38cc heads. I was wondering what kind of pistons i should get and i was wondering if the t5/45 transmission i have in my sohc 4.6 would bolt up to the teksid bell housing or if id be better off getting a t56, i would get the t45 rebuild to be able to hAndle the horsepower but wasnt sure if it would be worth it. I have many other questions but these are the questions i wasnt able to find searching around. I do know the 44cc and 38 cc on the heads affects compression i would just like a little more info on combinations to go with those heads. I have read that to have the 2v heads on the teksid block, it is required to drill a hole for the water passage but i was wondering what else i would need to do to get the heads to run smooth with the block. I appreciate any info or suggestions on the build and thank u in advance!
