Looks like I am going to port some LS heads

[MR.hp]

Got a set of 706 5.3 LS heads I found that I think need to be ported. Will be interesting to see what I can get out of them.

I think they're a smaller cc than the 853s that came on my LS1 which would give a slight comp bump.
Are the porting tools you used on cast gonna work?
