npi-pi intake plates

[Mitternacht]

Everywhere I look, there's adapter plates to use PI intakes on non-PI heads. Are there any plates out there to use my non-PI intake on PI heads?

hmm i have never heard of such adaptors, but may i ask why u would want to put a NPI intake on PI heads, im pretty sure u would gain about 30HP with PI manifold and only about 5-10HP with PI heads, and where do u find the adaptor plates for PI manifold to NPI heads?...thanks

well, i have done this, when all those intake started cracking back in the day, i put pi intakes on without using adapter plates, i just slightly modified the (PI) intake gaskets to make it all work, no leaks and a few more ponys to boot..
