i bought a set of stage 2.5 5.3 heads used that had a spring break. causing the valve to drop and broke the head of valve of. the head of the valve got wedged in the seat on the intake side. so i took the head to champion racing heads in palm coast. they fixed the seat but did a bad job! valve guide was also broke.
they called me saying it was ready so i drove an hour there to pic up. when i got there i inspected the head and found that they simply replaced seat and guide but did not fix the aluminum around guide that was cracked. there was a chunk of aluminum that was would have fell in my engine after a few heat cycles. i was told it was fine wich i knew it was not. the owner of the shop took a screw driver and with minimal pressure the piece fell off into the intake runner. i said see that would have went into my engine causing a blown engine. this peice was half the size of a dime and 3 times as thick. any way i told i was not happy with it. they fixed it "right" the next day. i drove back down there to pick up. they rewelded the broken spot and reported it. all looked well.
after gettin home i found that the intake and exhaust valve in that chamber they fixed was different than the valves that texas speed had in there. the only number i found was 27704 on the valve which i cant find any info on it. the exhuast valve is shorter by like .005 and intake is longer by .007 they gave me a intake valve to do my flycutting with wich also had the same number 27704 which is a 2.05 valve. they machined one of these down to a 2.02 to fit in my head. this valve is also alot heavier than my others.
so basically i need a new intake and exhaust valve for this chamber. also knoticed that the valve would not seat right. i took a light and put it up to the cumbustion chamber and looked down the intake runner and i see light around the valve. this would cause the loss in compression.
i paid this company 365.00 to fix my head so i all i had to do was bolt it on....yea right. there is more on this about the conversations tom the owner and i had. but it would take forever.
this is what happened due to spring failure. no ones fault.
