Purchased a set of heads from this place and all i can say,due to being naive and didn't follow my gut instinct i payed the price with one engine wiped out, $6000k.When i removed the heads and i took these to a pretty good local machinist, which i should have done (valuable lesson learn"t) he couldn't believe how poorly done these were assembled,valves too tight in the guides which caused valve to break at the base and you can imagine the end result.Valve tips were all at different heights,to his credit he did use decent parts but the work to set them up were pretty bad.I Emailed him a report which my machinist typed up on a company letter head to explain what happened and what caused it, with pictures he never replied which i expected! problem why he is trying to sell out due to his **** work and the come backs...AND he is supposed to be this Mopar Guru!!! Man i would not let him put oil on my push bike chain.As the saying goes got reamed good and proper with out the Vas! Once bitten twice shy.
I bought a 340 from this company website said $400 to upgrade from 360 to 340 block then quoted $600 & increased to $900 on the final invoice build was 340 E/Q heads Comp roller cam,roller lifters & 1.5 roller rockers ,eagle ibeams .
once i received i removed the masking tape & fitted a vacuum 650 Holley upon start up motor had a loud clatter shut down after 30 seconds & like you removed the heads
He have fitted KB243 pistons with E/Q heads & a .039" head gasket 3 pistons hit the head the other 5 were full of swarf & destroyed the pistons.Once i stripped the engine i found 4 of the spiral locks were hanging out.
Also machining swarf trapped in the main bearing shells.
John apologized & sent new pistons & rings which i sold as it had to be bored as machinist commented it looked like they had honed it with a drum sander
The machinist had to redo the complete motor yes they use the good parts but wouldn't have a clue about build quality.This was all on a engine that come with dyno results
but no engine number to prove it was for the motor tested.
all i used on the new build was the block, camshaft ,lifters & heads
i see the business is for sale but what does he offer he is working from his carport.
It took around 6 emails to get him to send a build sheet avoids all support paperwork for his builds ask you to call
Its strange how he loses so many emails
I guess the fact that his eba site is mostly written in red says it all.
Beware
