+4 stroker help

[BlastyJack]

I just had a quick question about a +4 stroker im thinking about building.... Would the oem head work without milling???

If you're going with the plus 4 crank you will have to have your cases trenched. And mod the head . or run the plus 3 and no trenching Of the cases nessasary. Slight fileling for rod clearancing on some cases.
And use supplied spacer plate. Or have ports adjusted and head and don't us spacer plate.
Best bet call ken oconner racing if going +4
Or +3 without spacer plate. They do all the machining
