They are SI Bronze guides. For your other questions I am sorry I can't speak intelligently about that. Hopefully a few with lots of experience with these engines can answer. Maybe Savington or Bogus will chime in here???

I chose these guides because I wanted to install new guides since we were removing the old ones for porting and the SI were a very popular choice.

I just finished porting my 95 1.8 non turbo...used the same pictures as a template that you probably did. very similar results when finished. i used clay and non stick cooking spray to keep track of my work, cramming it into the port and carefully removing it so that i could measure progress. i think i had to convince myself that it did increase power from 45-65k so that i didn't feel like i wasted a few hundred bucks experimenting. i was fairly warned before i started but am a tinkerer by nature.

lesson learned here..a turbo wouldn't care much about casting flaws or bowl shape, in applications under 250 h.p. IMO.... ordering turbo ingredients now.

I should be outside of that range so I guess maybe it is a good thing I did mine. Everything I have read would suggest you would have been better off just buying a BP4W head since they will flow better stock than a ported 95 head.....

Absolutely correct however, after all the small parts gathering, the $1000 price seemed absurd. In retrospect maybe it was not..

I would have sold you a 99 head for 400 with intake mani........1000 is too much.

Even then, some reconditioning and all the stuff to go back together and I was back at $1000. Maybe 900.

I'm gonna get on a dyno a.s.ap. for some real numbers. You know , so I can creep back up to the 1000 I didn't want to spend in the first place. Hahaha
