Is there any fitment problems with TTI- Big Block -A body

These guys can tell you more than I can. Sometimes aftermarket heads dont work to well with headers. The stage 6 heads on my brothers 70 cuda put the tubes of his tti's into the torsion bars. The angle of the exhaust ports is different. Had to bolt the headers down on a spare head and heat up all the pipes to bend em so they would fit. So ask around like your doing and let em know what head your using.
