[fmster]

Hi to all. How Do you guy's get an accurate imprint to port the intake and heads to match perfect? Thanks.

Install the intake manifold to the heads with gasket installed. drill a very small hole through the intake manifold by a bolt hole until you make a mark into the head. now you can disassemble and you can now place the intake manifold over the intake or heads and trace exactly how much to port by lining up the small hole
