There are videos on youtube of p&p ing but most of them are on big v8s that have much bigger ports. On the 7m the ports are much smaller and harder to work on. On mine I tried to do it myself and got sick of it and had the guy at the machine shop do it for me. He spent about 4 hours grinding away as well as a valve job and reshiming for $500.

how thats fairly cheep! but yeah ill be doing a complete overhaul of the engine so everything comes out and new gets put back in. easyer said then done plus i the work on the head and block. hope this goes smother then what im thinking it will lol. wont know till i try. and i will be asking questions cause the haynes repair manual i has gives more info in the 5M's and basicly skips over the 86.5 and 87's and then gos directly to the 89-92 7m-GTE witch are similar but still. ill be using Cygnus X1 witch as everyone has said the holy bible to the supra's! lol
