I'm thinking about swapping over to Trick Flow aluminum heads but can't quite figure out which of the six available (maybe) versions to get.
What makes it hard is that I don't have super reliable info on my engine build done by the PO. I know the pistons are flat with valve reliefs.
Cam is - I think - this one:
I have a set of Crower Stainless Enduro rockers (thanks @davidnunn )
I guess it comes down to chamber size and valve spring size but I don't know which to choose. Thanks in advance!
