Hello All, I have a Trans-Am with a four bolt small block Chevy and a stroker crank and rods. I now have run in to an issue that I need some advise with. My head's have raised exhaust ports by .300" and angle spark plug's, I have patriot shorty headers and I would like to know before I try and fit them, if the raised port's will be an issue or ok ? from what I have read is appears that it just means that the Exhaust header will sit .300" higher that stock, is this right ? thanks Paul.
