My project has hit a stop for a week or two. I ordered "made in the USA" vortec heads from Jegs. I wanted to keep the ports small and the EQ heads were rumored to have larger ports in Brezinski's Videos and other posts. The first Jegs 514080 head was a little ugly under the valve seats but OK. It looked like it had some type of liner on the valve guides. They were advertised has having bronze guides. I cleaned it up a little and went the the next one. The second head actually looked a little cleaner port wise but had a giant gack on one of the valve stems. Like there was something in the guide and they beat it through anyway. I returned that head and the replacement showed up today with a promaxx number on the box and no "made in the USA" Its the same ugly casting but no liners in the guides and the retainer to seal clearance is only .420" When the other head was .475" clearance. It was a big mistake to order these but live and learn. I think I will call Jegs in the morning and see what can be done.
