79795, Question on port and polish
Posted by mitifto, Aug-28-04 05:01 PM
Is it really necessary to remove the valves prior to port and polish or can you just clean the ports without removing them???

how are you going to port it if you don't remove the valves?

the valves are at the end of the intake and exhaust ports. You can port and polish to the valve. Just wondering if I had to remove them to do a full port and polish. Don't have the tools to remove the valves.

if you do not plan to P/P the bowl area then you dont need to remove the valves, you will need to open each to clean the ports out though. You must use extreme care not to knick any of the valve stems while polishing or ports......knicked valve stem can heat up and break on you...the rest is history

All you would be doing is a gasket match if you don't, the reak restriction is not at the beginning of the head ports.

No offense here, but porting a head is not something you should do if you haven't done any P&P before.

Seconded.

And, for what its worth, the right way to do it is with the valves out. if you're not going to do it right, then don't do it at all.

Just drill through the valves. That'll get them out of the way, and your motor will flow a lot more at TDC that way.

At least the screenname is very appropriate to the level of knowledge presented in this post.
